MP3 support for OSX?

I’m trying to bring a Windows pygame program over to Mac OSX (10.3).
On the Mac I get “Module format not recognized” when trying to play
MP3s. My guess is that this means the current SDL on the Mac is
built without MP3 support. Does anybody have an OSX build of SDL (or
SDL_mixer) supporting MP3 that I can use?


P.S. I’ve tried downloading the source for SDL_mixer, but I get lots
of errors trying to compile it.
