When I run
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/apc.so' - /usr/lib64/php/modules/apc.so: undefined symbol: php_pcre_exec in Unknown on line 0
This isn't my first rodeo. I've setup APC multiple times. This is a MediaTemple Dedicated Virtual 4.0 with Plesk 11. Plesk 11 is the only thing essentially different from the other servers I've set this up on.
I've verified that
pcre-devel is installed. I've compiled APC from source as well as used pecl to install it. No difference.
I also tried downgrading to APC 3.0.19, with no love.
