1- No sound file support on OSX
Looks like you need to get pyAo and libao installed and going.

2- No ogg support, since it's not finding any of my OGG's
Ditto for vorbis.

You will probally have to fix up issues with pyOgg and pyVorbis as well.
I don't have a Mac so I don't know if any of the above are actually usefull but its just what I found with google.
