To finish the install of pecl-APC, you need
to enable the module by using the following command

    # /usr/local/sbin/phpxs -a apc

If you already have Apache running on your machine,
you should not use "apachectl restart" - instead,
you should fully stop and then restart the server.

You'll also need to configure APC using various 
settings in php.ini.  See /var/www/pecl-APC/INSTALL
for details.
