apache2 & php

[Kyrath. (AKA Rob)]

I recently compiled and installed apache2.  Now, I'm trying  to enable the php module.  However, when php is accessed, I get a missing library error.

libmm.so.13

I can't find it anywhere on my system and I can't tell whether this library  belongs to a general lib package or is specifically a php library. 

Anyone know anything about this lib or perhaps where I might find it?
