Updating php on OS 10.2.3 server?

I'd like to upgrade my php install on a 10.2.3 server, but all the "easy" avenues (ie Marc Liyanage, PHP 4.3 install from version tracker,..) work, but break apple_auth_module. I need that mod,...anyone got a way to do this? I'm still learning the unix side of things, so compiling php from source is over my head, particularly as I don't know which of the many options I need and don't need.
