If you compile it on a machine that has only mysql-5.x and
mysql-devel-5.x on it, it should then link against the proper files.

Hopefully you are making RPMS and not doing installs from source.  I
would also try to stay with the CentOS RPMS (in CentOS-4 we have
php-4.3.9) as you know those will be supported and get security updates
until 2012 ... BUT php-4 will most likely not last that long from php.net.

You should (though I have not tried it) be able to compile the php-4.3.9
SRPMS from CentOS-4 on CentOS-3.  You might also get the mysql SRPMS for
MySQL from the CentOS-4 CentOSPlus repo and recompile on CentOS-3.

If I was going to do mysql-5 and php-4 on CentOS-3, that is what I would
do ... though I would most likely do it on CentOS-4 instead and get a
newer version of apache too.
