PORT-MODULES(5)

NAME
port-modules - documentation and conventions used in port modules

DESCRIPTION
The OpenBSD Ports framework is based on a gigantic makefile named bsd.port.mk(5).

In order to curb unwieldy growth, parts of the framework that are not always needed have been set apart in optional files called port modules, which are retrieved as needed through the MODULES variable of bsd.port.mk(5).

Some of these modules correspond to basic mechanisms which are not always needed, such as GNU autoconf, or perl5.

Other modules correspond to shortcuts for using some other ports as dependencies without needing to hardcode too much, such as libiconv or the qt ports.

THE MODULES LOOK-UP MECHANISM
The variable MODULES should contain a list of module names. Some core modules are a single word, all other modules should be ${PKGPATH}. If the module is some/dir/portname, the ports framework will look for a file named ${PORTSDIR}/some/dir/portname/portname.port.mk and include it.

Most modules should conform to this syntax. The historic practice of having a redirection file directly under ${PORTSDIR}/infrastructure/mk is deprecated for new modules.

Modules may refer to each other. The modules mechanism has specific recursion handling such that adding MODULES += foo/bar to a module will work as expected.

NAMING CONVENTIONS
Since there is no actual scope in makefiles, everything defined within a module will be global to the ports framework, and thus may interfere with other ports.

As far as possible, all variables and targets belonging to a module named some/dir/foo should be named MODFOO_* and modfoo_*.

Following the same conventions as bsd.port.mk(5), internal variables and targets not intended for user consumption should be named _MODFOO_* and _modfoo_*.

For instance, if a module wants some value to be available for the rest of the world, it should define MODFOO_VARNAME, with a name matching the basic infrastructure as far as possible. That is, a port that defines specific dependencies will usually define MODFOO_WANTLIB, MODFOO_LIB_DEPENDS, and MODFOO_RUN_DEPENDS, as appropriate.

As an exception to the naming mechanism, some ports have several distinct versions in the ports tree, say x11/qt3 and x11/qt4. Instead of using the namespace MODQT3*, variables will usually drop the version suffix and be simply called MODQT_* so that a port using the module can be switched from version to version without needing to change everything.

It is highly desirable to define names in both namespaces for such ports, for example to define both MODQT3_LIB_DEPENDS and MODQT_LIB_DEPENDS. Normal client ports will use MODQT_LIB_DEPENDS, but a port may exceptionally import both modules with MODULES += x11/qt3 x11/qt4 and differentiate between qt3 and qt4 needs with MODQT3_LIB_DEPENDS and MODQT4_LIB_DEPENDS. See print/poppler for an example.

OVERRIDING TARGET BEHAVIOR
The main framework contains several hooks that allow ports to override normal behavior. This evolved as an ad-hoc framework, where only hooks that turned out to be needed were added. If several modules define the same hook, hook behaviors will be invoked in sequence.

patch
    There is a post-patch hook that can be activated by defining MODFOO_post-patch. It will be run right after post-patch and before REORDER_DEPENDENCIES touches things.

configure
    There is a pre-configure hook that can be activated by defining MODFOO_pre-configure. It will be run right after pre-configure. The normal do-configure behavior is to invoke all MODFOO_configure contents that are defined in CONFIGURE_STYLE. By default, configure will do nothing.

    Some CONFIGURE_STYLE values, namely perl, gnu, imake, automake, autoconf, and autoupdate will automatically import the correct module. User-defined modules must both add to CONFIGURE_STYLE and import the correct module to override behavior.

    Contrary to other hooks, module behavior is not invoked in addition to do-configure, but as the normal configure process. If do-configure is overridden, normal hook processing will not happen.

fake
    There is a pre-fake hook that can be activated by defining MODFOO_pre-fake. This will be invoked right after mtree(8), and before the normal pre-fake behavior.

    This can occasionnally be used for ports that require some specific fake installation setup that will be provided by runtime dependencies.

install
    There is a post-install hook that can be activated by defining MODFOO_post-install. This will be invoked at the end of install, right after the normal post-install behavior.

Some targets, such as do-build or do-install, can't be overridden simply. A module that, for instance, requires specific do-build behavior should do so in two steps:

•   Define a variable named MODFOO_BUILD_TARGET that contains the commands necessary for do-build:

        MODFOO_BUILD_TARGET = cmd1; cmd2

•   Override do-build only if it's not already defined by the port proper:

        .if !target(do-build)
        do-build:
        	@${MODFOO_BUILD_TARGET}
        .endif

That way, if several modules require specific actions for those targets, the end user can choose the appropriate order in which to run the actions:

    do-build:
    	@${MODBAR_BUILD_TARGET}
    	@${MODFOO_BUILD_TARGET}
    	...

OVERRIDING VARIABLE BEHAVIOR
Some variables can be overridden by modules. Be very cautious, as this can make the module difficult to use, or interact badly with other modules. As a rule, always provide the override as:

    VARIABLE ?= value

and provide a module-specific variable with the same value:

    MODFOO_VARIABLE = value.

The following variables can be overridden in a relatively safe fashion: ALL_TARGET, CONFIGURE_SCRIPT, DESTDIRNAME, DIST_SUBDIR, DISTNAME, DISTFILES, EXTRACT_SUFX, FAKE_FLAGS, FETCH_MANUALLY, HOMEPAGE, IGNORE, IS_INTERACTIVE, LIBTOOL_FLAGS, MAKE_FILE, MASTER_SITES, MULTI_PACKAGES, NO_BUILD, NO_TEST, PATCH_LIST, PKG_ARCH, PKGNAME*, PREFIX, TEST_TARGET, TEST_IS_INTERACTIVE, REORDER_DEPENDENCIES, SEPARATE_BUILD, SHARED_ONLY, USE_GMAKE, USE_LIBTOOL.

The following variables can be added to in a relatively safe fashion: BUILD_DEPENDS, CATEGORIES, CONFIGURE_ARGS, CONFIGURE_ENV, ERRORS, FAKE_FLAGS, FLAVOR, FLAVORS, INSTALL_TARGET, LIB_DEPENDS, MAKE_ENV, MAKE_FLAGS, PKG_ARGS, PSEUDO_FLAVORS, TEST_DEPENDS, REORDER_DEPENDENCIES, RUN_DEPENDS, SUBST_VARS, WANTLIB.

SPECIFIC MODULE INTERACTIONS
Some modules correspond to extra ports that will be used mostly as BUILD_DEPENDS or RUN_DEPENDS. Such modules can safely append values directly to the BUILD_DEPENDS, RUN_DEPENDS, LIB_DEPENDS, and WANTLIB variables, as long as they also define module-specific variables for all runtime dependencies.

Simple client ports will use the module directly, and thus inherit extra build and runtime dependencies.

More sophisticated ports can use MULTI_PACKAGES to select specific behavior: build-time dependencies will always be needed. Runtime dependencies will be selected on a subpackage basis, since runtime dependencies such as LIB_DEPENDS-sub do not inherit the default LIB_DEPENDS value. The client port's author must only bear in mind that external modules may add values to the default WANTLIB, LIB_DEPENDS, and RUN_DEPENDS, and thus that it is not safe to inherit from it blindly.

Modules are imported during

    .include <bsd.port.mk>

Thus they can be affected by user choices such as setting a variable to Yes or No. Modules may make decisions based on documented MODFOO_BEHAVIOR values.

When modules are processed, only a few bsd.port.mk(5) variables are already defined. Modules may depend upon the following variables already having a sane value: DISTDIR, LOCALBASE, NO_DEPENDS, PKGPATH, PORTSDIR, X11BASE and all arch-dependent constant from bsd.port.arch.mk(5), such as PROPERTIES or NO_SHARED_ARCHS. Note that this is only relevant for tests. It is perfectly okay to define variables or targets that depend on the basic ports framework without having to care whether that variable is already defined, since make(1) performs lazy evaluation.

CORE MODULES DOCUMENTATION
The following modules are available.

apache-module

converters/libiconv

cpan
    For perl ports coming from CPAN. Wrapper around the normal perl module that fetches the file from the correct location depending on DISTNAME, and sets a default PKGNAME. Also affects TEST_DEPENDS, CONFIGURE_STYLE, PKG_ARCH, and CATEGORIES.

    Some CPAN modules are only indexed by author, set CPAN_AUTHOR=ID to locate the right directory.

    If no HOMEPAGE is defined, it will default to http://search.cpan.org/dist/${DISTNAME:C/-[^-]*$//}/

    User settings: set CPAN_REPORT to Yes, CPAN_REPORT_DB to a valid directory, and CPAN_REPORT_FROM to a valid email address to automate the reporting of regression tests to CPAN.

    If MODCPAN_EXAMPLES is set, the following variables will be set. MODCPAN_EXAMPLES_DIST will hold the default directory in the distfile with example scripts. MODCPAN_EXAMPLES_DIR will be set to the standard installation directory for examples. Sets the post-install target if none has been defined to install the examples, otherwise MODCPAN_POST_INSTALL should be used as such:

        post-install:
        	...
        	${MODCPAN_POST_INSTALL}

devel/cmake

devel/dconf
    Sets CONFIGURE_ARGS, BUILD_DEPENDS and RUN_DEPENDS. This module is used by ports installing gsettings schemas under ${PREFIX}/share/glib-2.0/schemas/. It requires the following goo in the PLIST:

        @exec %D/bin/glib-compile-schemas %D/share/glib-2.0/schemas >/dev/null
        @unexec-delete %D/bin/glib-compile-schemas %D/share/glib-2.0/schemas >/dev/null

devel/gconf2
    A link from gconftool-2(1) to true(1) will be put at the front of the path. Sets CONFIGURE_ARGS, BUILD_DEPENDS and RUN_DEPENDS. According to the values of MODGCONF2_LIBDEP, sets LIB_DEPENDS. User settings: set MODGCONF2_SCHEMAS_DIR to the directory name under ${LOCALBASE}/share/schemas/ where schemas files will be installed.

devel/gettext

devel/pmk
    Sets CONFIGURE_SCRIPT, CONFIGURE_ARGS and MODPMK_configure. It appends devel/pmk to BUILD_DEPENDS.

devel/scons
    Adds devel/scons to BUILD_DEPENDS. Sets MODSCONS_BIN and MODSCONS_ENV. Also defines an overridable MODSCONS_FLAGS. It provides a do-build and do-install targets that can be overridden in the port Makefile.

devel/waf
    Adds devel/waf to BUILD_DEPENDS, lang/python to MODULES, and provides do-configure, do-build, do-install and post-install targets. do-build, do-install and post-install can be overridden in the port Makefile.

fortran
    Sets MODFORTRAN_LIB_DEPENDS, MODFORTRAN_WANTLIB, MODFORTRAN_BUILD_DEPENDS. Set MODFORTRAN_COMPILER to `g77' or `gfortran', depending on what the port requires. The default is `g77'. The dependencies are chosen according to COMPILER_VERSION and MODFORTRAN_COMPILER.

gcc4
    If COMPILER_VERSION is not gcc4 (defined by /usr/share/mk/bsd.own.mk), and architecture is in MODGCC4_ARCHS, then the gcc4 compilers will be put at the front of the path. By default, only C language support is included by this module. If other languages are needed, they must be listed in MODGCC4_LANGS (e.g. c++, fortran). The MODGCC4_VERSION variable can be used to change the version of gcc. By default gcc 4.6 is used. If MODGCC4_LANGS contains c++, this module provides MODGCC4_CPPLIBDEP and MODGCC4_CPPWANTLIB.

gnu This module is documented in the main bsd.port.mk(5) manpage.

imake
    This module is documented in the main bsd.port.mk(5) manpage.

java
    Set MODJAVA_VER=x.y to use exactly the JDK x.y, MODJAVA_VER=x.y+ to use any x.y or higher version. Set MODJAVA_JRERUN=Yes if the port only needs the JRE at runtime. The module sets JAVA_HOME, ONLY_FOR_ARCHS, MODJAVA_RUN_DEPENDS, MODJAVA_SHARE_DIR, MODJAVA_JAR_DIR, MODJAVA_EXAMPLE_DIR and MODJAVA_DOC_DIR. It appends to BUILD_DEPENDS, RUN_DEPENDS, CATEGORIES and SUBST_VARS. If MODJAVA_BUILD=ant then this module provides MODJAVA_BUILD_DIR, MODJAVA_BUILD_FILE and MODJAVA_BUILD_TARGET_NAME, as well as a do-build target (if not already defined). It heeds NO_BUILD.

lang/clang
    Similar to gcc3 and gcc4 modules. If architecture is in MODCLANG_ARCHS, the CLang compilers will be put at the front of the path. By default, only C language support is included by this module. If other languages are needed, they must be listed in MODCLANG_LANGS (e.g. c++). Sets MODCLANG_VERSION which is also appended to SUBST_VARS.

lang/erlang

lang/ghc
    Sets ONLY_FOR_ARCHS, MODGHC_VER, BUILD_DEPENDS, and RUN_DEPENDS. Build and further actions are based on the list of values in MODGHC_BUILD:

    nort
        no runtime dependency on lang/ghc and hs- prefix will not be added,

    cabal
        get the typical Cabal targets defined,

    haddock
        generate API documentation using devel/haddock,

    register
        create and include register/unregister scripts,

    hackage
        the distfiles are available on Hackage.

    Also affects CATEGORIES, CONFIGURE_STYLE and SUBST_VARS. do-build, do-install and do-test targets are provided if the port itself didn't set them. If register has been set, the PLIST needs to be modified in order to add the relevant @exec/@unexec lines. This module will run the Setup script and ensure the documentation will be built (if haddock has been set), and that the package is registered as a library usable by lang/ghc (if register has been set). Extra arguments and environment additions for the Setup configure command can be specified with MODGHC_SETUP_CONF_ARGS and MODGHC_SETUP_CONF_ENV.

lang/lua
    Sets MODLUA_BIN, MODLUA_DATADIR, MODLUA_DEP, MODLUA_DEP_VERSION, MODLUA_DOCDIR, MODLUA_EXAMPLEDIR, MODLUA_INCL_DIR, MODLUA_LIB, MODLUA_LIBDIR, MODLUA_VERSION, MODLUA_WANTLIB. Appends to CATEGORIES. Also appends to BUILD_DEPENDS, unless NO_BUILD has been set to Yes. Also appends to RUN_DEPENDS, unless MODLUA_RUNDEP is set to No. Appends MODLUA_VERSION, MODLUA_LIB, MODLUA_INCL_DIR, MODLUA_EXAMPLEDIR, MODLUA_DOCDIR, MODLUA_LIBDIR, MODLUA_DATADIR, MODLUA_DEP, MODLUA_DEP_VERSION, MODLUA_BIN to SUBST_VARS. MODLUA_DEFAULT_VERSION is set to 5.1. MODLUA_VERSION is set to MODLUA_DEFAULT_VERSION by default. Ports can be built with two lua versions. If no FLAVOR is set it defaults to MODLUA_DEAFULT_VERSION. Otherwise the FULLPKGNAME is adjusted, if MODLUA_SA is not set. In order to set a build, run or test dependency on a lua port, use the following, which will propagate the currently used flavor: MODLUA_BUILD_DEPENDS, MODLUA_TEST_DEPENDS, MODLUA_RUN_DEPENDS.

lang/mono
    Sets MODMONO_ONLY_FOR_ARCHS, CONFIGURE_ENV, MAKE_FLAGS, MODMONO_BUILD_DEPENDS and MODMONO_RUN_DEPENDS. If MODMONO_DEPS is set to Yes, lang/mono is appended to BUILD_DEPENDS and RUN_DEPENDS. If MODMONO_NANT is set to Yes, NANT and NANT_FLAGS are set, devel/nant is appended to BUILD_DEPENDS and a do-build and do-install targets are provided to use nant for building. If these targets are already defined, one can use MODMONO_BUILD_TARGET and MODMONO_INSTALL_TARGET instead in the corresponding target. DLLMAP_FILES defines in which files the module will substitute hardcoded shared library versions using a post-configure target.

lang/node
    Adds common dependencies to RUN_DEPENDS and BUILD_DEPENDS. Recognizes two additional types of CONFIGURE_STYLEs, "npm" and "npm ext". "npm ext" should be used for npm packages that contain C++ extensions which need to be compiled. "npm" should be used for other npm packages. If regression tests are included that can be run using devel/node-expresso, append "expresso" to CONFIGURE_STYLE. devel/node-expresso will be appened to TEST_DEPENDS and a default MODNODE_TEST_TARGET will be defined, along with a do-test target if it has not already been set. If "expresso" isn't appended to CONFIGURE_STYLE, TEST_TARGET will be set to "test". One of these two CONFIGURE_STYLEs should be used or the module doesn't affect anything except RUN_DEPENDS and BUILD_DEPENDS. Requires NPM_NAME to be set to the name of the npm package. Uses NPM_NAME and NPM_VERSION to set DISTNAME, and PKGNAME, and MASTER_SITES. If the npm package depends on other npm packages, the npm package names it depends on should be listed in MODNODE_DEPENDS. Adds default do_build and do_install tasks, and you can reference the default implementations via MODNODE_BUILD_TARGET and MODNODE_INSTALL_TARGET.

lang/ocaml
    Sets OCAML_VERSION. Appends to BUILD_DEPENDS and MAKE_ENV. This selects a %%native%% plist fragment and ocaml_native property depending on whether the architecture supports native compilation. If dynamic linking is supported on the native architecture, the %%dynlink%% plist fragment and ocaml_native_dynlink property is set.

lang/php/pecl
    Used for ports for PHP PECL extensions. Sets default MASTER_SITES, HOMEPAGE, EXTRACT_SUFX, DESTDIRNAME, MODPHP_DO_SAMPLE, MODPHP_DO_PHPIZE, AUTOCONF_VERSION, AUTOMAKE_VERSION, LIBTOOL_FLAGS. Provides a default TEST_TARGET and TEST_FLAGS unless NO_TEST or a do-test target is defined. Adds common dependencies to RUN_DEPENDS and BUILD_DEPENDS. Sets a default PKGNAME and appends to CATEGORIES.

lang/python
    Sets MODPY_VERSION, MODPY_BIN, MODPY_INCDIR, MODPY_LIBDIR, MODPY_SITEPKG, MODPY_SETUP, MODPY_WANTLIB, MODPY_LIB_DEPENDS, MODPY_RUN_DEPENDS, MODPY_BUILD_DEPENDS and MODPY_ADJ_FILES. Appends to RUN_DEPENDS unless MODPY_RUNDEP is set to No. Appends to BUILD_DEPENDS unless MODPY_BUILDDEP is set to No or NO_BUILD is set to Yes. MODPY_VERSION is the default version used by all python modules. Ports which use the setuptools module should set MODPY_SETUPTOOLS to Yes. All ports that generate egg-info files should set MODPY_EGG_VERSION to the version string used by the port's setup.py setup() function. Extra arguments to the build and install commands can be passed via MODPY_DISTUTILS_BUILDARGS and MODPY_DISTUTILS_INSTALLARGS. If any files have a python shebang line which needs to be replaced using MODPY_BIN, list them in MODPY_ADJ_FILES. These are prefixed with WRKSRC and replaced automatically at the end of pre-configure. Also affects CATEGORIES, MAKE_ENV, CONFIGURE_ENV, SHARED_ONLY, and SUBST_VARS. May affect the test target.

lang/ruby
    See ruby-module(5).

lang/tcl
    Sets MODTCL_VERSION, MODTCL_BIN, MODTCL_INCDIR, MODTCL_LIBDIR, MODTCL_BUILD_DEPENDS, MODTCL_RUN_DEPENDS, MODTCL_LIB, MODTCL_LIB_DEPENDS, and MODTCL_CONFIG. MODTCL_VERSION is the default version used by all Tcl ports and may be overridden. Provides MODTCL_TCLSH_ADJ and MODTCL_WISH_ADJ shell fragments to patch the interpreter path in executable scripts. Also affects CATEGORIES and SUBST_VARS.

perl
    This module is documented in the main bsd.port.mk(5) manpage.

textproc/intltool
    Sets MODINTLTOOL_OVERRIDE. textproc/intltool is added to BUILD_DEPENDS. MODINTLTOOL_OVERRIDE changes the paths of INTLTOOL_EXTRACT, INTLTOOL_MERGE and INTLTOOL_UPDATE to use the installed versions of intltool-extract, intltool-merge and intltool-update, instead of the version's packages into the distfile of the port using this module. Also affects CONFIGURE_ENV, MAKE_ENV and MAKE_FLAGS by appending MODINTLTOOL_OVERRIDE to them.

www/drupal6
    This module is legacy. drupal6 is still supported, but new work should mostly happen in drupal7 land.

www/drupal7
    Can be used to install plugins (default), themes if MODDRUPAL_THEME is yes, or languages packs if DRUPAL_LANG is set to the desired language.

    The module will set or add to default values for HOMEPAGE, MASTER_SITES, PREFIX, DIST_SUBDIR, CATEGORIES, PKG_ARCH, WRKDIST, RUN_DEPENDS. Drupal modules normally don't have any build part, just an installation part that defaults to copying the plugin/theme/language files into the right location through MODDRUPAL_INSTALL.

    The module sets DRUPAL to drupal7, DRUPAL_ROOT to htdocs/${DRUPAL} DRUPAL_MODS to ${DRUPAL_ROOT}/site/all/modules DRUPAL_THEMES to ${DRUPAL_ROOT}/site/all/themes and DRUPAL_TRANSLATIONS to ${DRUPAL_ROOT}/profiles/standard/translations. So, by default, modules and themes are installed for all sites, and translations are activated at install.

    DRUPAL_OWNER, DRUPAL_GROUP are set to root, daemon, since drupal doesn't need to write to any file except the files/ directory and the site settings (those belong to www instead).

    Translations are handled by setting DRUPAL_LANG to the language letter code, and by setting LANGFILES to a list of module names/version pairs.

    With drupal7, all translations have been put in separate .po files. It has been deemed simplest to pack all translations for a given language into a single package, since translations for non installed modules won't affect anything.

www/horde

www/mozilla
    Sets PKGNAME, HOMEPAGE, MASTER_SITES, DISTNAME, USE_GMAKE, ONLY_FOR_ARCHS and SHARED_ONLY. EXTRACT_SUFX defaults to .tar.bz2.

    Adds common dependencies to LIB_DEPENDS, WANTLIB, RUN_DEPENDS and BUILD_DEPENDS. Sets common CONFIGURE_ARGS, MAKE_ENV and CONFIGURE_ENV. Sets MOB variable as source directory and MOZ as target directory within do-install.

    Individual port Makefile must set MOZILLA_PROJECT, MOZILLA_CODENAME, MOZILLA_VERSION, MOZILLA_BRANCH, MOZILLA_LIBS and MOZILLA_DATADIRS variables. Port can also append values to MOZILLA_SUBST_FILES which contains the list of files to run SUBST_CMD on during pre-configure, and MOZILLA_AUTOCONF_DIRS which contains the list of dirs where AUTOCONF will be run during pre-configure.

www/pear
    Used for PHP PEAR ports. Sets default MASTER_SITES, EXTRACT_SUFX, PKGNAME. Sets PREFIX to /var/www. Sets NO_TEST unless a do-test target is defined. Adds common dependencies to RUN_DEPENDS and BUILD_DEPENDS, sets MAKE_FILE and FAKE_FLAGS appropriately. Makes PEAR_LIBDIR and PEAR_PHPBIN available for use in the port. Sets a default PKGNAME and appends to CATEGORIES.

www/plone
    Sets MODPLONE_VERSION and MODZOPE_VERSION. MODPLONE_VERSION is the default version used by all Plone ports and may be overridden. It appends www/plone to RUN_DEPENDS and also sets NO_TEST to Yes.

www/zope

x11/gnome
    If both GNOME_PROJECT and GNOME_VERSION are set, this module defines DISTNAME, VERSION, MASTER_SITES, adds x11/gnome to CATEGORIES and EXTRACT_SUFX will default to .tar.xz if unset. Also unconditionally sets USE_GMAKE. If MODGNOME_ICON_CACHE=Yes, a dependency on x11/gtk+2,-guic is appended to MODGNOME_RUN_DEPENDS. Unless NO_BUILD=Yes, CONFIGURE_SHARED is appended to CONFIGURE_ARGS, CPPFLAGS="-I${LOCALBASE}/include" and LDFLAGS="-L${LOCALBASE}/lib" are appended to CONFIGURE_ENV and textproc/intltool is appended to MODULES. If none of AUTOCONF_VERSION nor AUTOMAKE_VERSION are defined, then "--disable-maintainer-mode" is appended to CONFIGURE_ARGS. Certain build/run dependencies and configure arguments and environment can be set by appending gi, gtk-doc, vala and/or yelp to MODGNOME_TOOLS. They are disabled otherwise. If MODGNOME_TOOLS is set to yelp, textproc/itstool and x11/gnome/doc-utils are appended to MODGNOME_BUILD_DEPENDS. Also, x11/gnome/yelp is appended to MODGNOME_RUN_DEPENDS, and MODGNOME_RUN_DEPENDS_yelp is set for use with multi packaged ports. This option is to be used when any files are installed into share/gnome/help/ or page files are installed into share/help/. MODGNOME_BUILD_DEPENDS and MODGNOME_BUILD_DEPENDS are appended to the corresponding BUILD_DEPENDS and RUN_DEPENDS.

x11/gnustep

x11/kde

x11/qt3 and x11/qt4
    Both qt modules share a common MODQT_* namespace for simple ports. The qt3 module also defines the same variables under MODQT3_* and the qt4 module also defines the same variables under MODQT4_*, to allow ports to use both modules, such as print/poppler.

    Those modules define MODQT*_LIBDIR as the libraries location, MODQT*_INCDIR as the include files location , MODQT*_QTDIR as the global qt directory location , MODQT*_CONFIGURE_ARGS as standard GNU configure-style parameters to locate the include and libraries.

    The location of qt specific tools moc and uic is available through MODQT*_MOC and MODQT*_UIC. MODQT*_OVERRIDE_UIC controls whether the default setup will force a value of UIC or not. The value of MOC is always forced to ${MODQT*_MOC}. qt4 includes pkg-config(1) files under a specific location recorded in MODQT_PKG_CONFIG_PATH. qt3 requires the use of MODQT3_PLUGINS to correctly locate plugins.

    The modules add to CONFIGURE_ENV, MAKE_ENV and MAKE_FLAGS. They define appropriate MODQT*_LIB_DEPENDS and MODQT*_WANTLIB. Note that qt4 has split its code over several libraries, so the basic WANTLIB only refers to QtCore. Other libraries should be added as needed.

x11/tk
    Sets MODTK_VERSION, MODTK_BIN, MODTK_INCDIR, MODTK_LIBDIR, MODTK_BUILD_DEPENDS, MODTK_RUN_DEPENDS, MODTK_LIB, MODTK_LIB_DEPENDS, and MODTK_CONFIG. MODTK_VERSION is the default version used by all Tk ports and may be overridden. Automatically adds the lang/tcl module, provides a default MODTCL_VERSION to match MODTK_VERSION, and affects CATEGORIES and SUBST_VARS. Note the MODTCL_WISH_ADJ shell fragment in the lang/tcl module.

x11/xfce4
    Sets DIST_SUBDIR, EXTRACT_SUFX, CONFIGURE_STYLE, CONFIGURE_ENV and USE_GMAKE. If MODXFCE_ICON_CACHE is set to yes, it adds x11/gtk+2,-guic to RUN_DEPENDS. Unless XFCE_NO_SRC is set, devel/gettext and textproc/intltool are added to MODULES. Also affects CATEGORIES.

    Xfce ports can be divided into five categories: core libraries and applications, goodies, artwork, thunar plugins, and panel plugins. HOMEPAGE, MASTER_SITES and DISTNAME are built using XFCE_VERSION (which defaults to XFCE_DESKTOP_VERSION if not set) and either XFCE_PROJECT, XFCE_GOODIE, XFCE_ARTWORK, THUNAR_PLUGIN or XFCE_PLUGIN. One of the latter has to be provided by the port Makefile.
