Building 5.2.12 w/MySQL on RedHat 64bit

Hi, I am trying to build PHP 5.2.12 on RHEL ES5 (the latest and greatest Redhat) 64bit. Why do I want to build PHP when Redhat includes PHP? The distro includes PHP 5.1.6 and our CMS (ModX) doesn¹t get along with 5.1.6 because of errors in the PDO layer. Now that I¹ve gotten that off my chest, when I run the configure, I get the error: checking for MySQL support... yes checking for specified location of the MySQL UNIX socket... no checking for MySQL UNIX socket location... no configure: error: Cannot find libmysqlclient under /usr. Note that the MySQL client library is not bundled anymore! The libmysqlclient libs are in /usr/lib64 and not /usr/lib (which contains 32 bit libs). I have tried simply ‹with-mysql, ‹with-mysql=/usr/lib64 and ‹with-mysql=/usr/lib64/mysql. Any idea how to successfully tell configure where to look?
