I am attempting to call the monosodium glutamate_get_queue() inside a CentOS 64 bits server.

I have downloaded the php sources and that i have put together the pcntl extensions following a steps:

cp modules/* /usr/lib64/php/modules/
cp modules/* /usr/lib/php/modules/

After i run php -m the module seems within the list. It is possible to method to solve this issue without producing php using the --enable-sysvmsg?

No, you have to compile it with --enable-sysvmsg.
