Hi, php-pecl-apc have been retired from rawhide repository. php-pecl-apcu is a dropin alternative for user cache and is also available in F18, F19 and EPEL6 (testing). It's time to switch and test. Remi. P.S. opcode cache is now provided by zend-opcache (php 5.5) or php-pecl-zendopcache (php 5.3 / 5.4), the official PHP project opcode cache.
