[CentOS] PHP Extensions

Hi all,

I have a problem, I'm running CentOS 4.3 and I just installed php with 
yum, later I realize that I nedd LDAP support so I download the php-ldap 
rpm with yum, everything was OK...but now..the problem is that I need 
Informix support, so I search for a php-ifx module to see if it 
exist...but no.
So, what are my options? recompile a fresh new php with informix 
support...loosing the automatic updates with yum... or compile php with 
informix support in another machine and then copy the "informix.so" to 
"/usr/lib/php4/"? will that work?
