Compile/install PHP with MySQL extension! [Problem]

[teamjoc]

"e107 requires PHP to be installed or compiled with the MySQL extension to work correctly, please see the MySQL manual for more information."

That's the message I got when I tried to install e107 on the webserver.
I am on CentOS 5.2 Remote Desktop (kde)
Anyway I don't think that doesn't matter, fact is: how to I compile that PHP with MySQL or whatever to like make e107 and other e107 based systems (like PHPNuke) work?

I need this help very quick as I have made my clanmembers and recruits waiting for a very long time...

Thanks in advance to all who helped me

yum install php php-mysql

Restart Apache afterwards.
