OS X SDL_Mixer framework bundle with libmad anywhere?

I’ve tried for the past two days to build SDL_Mixer with libmad instead
of smpeg on the Mac, but it’s just not possible; it seems I’ve no idea
how to do that and following the docs doesn’t work. I’ve already lost a
bunch of my hair due to this, so I’d like to ask if anyone has a
Framework bundle for OS X (PPC and Intel) that comes with libmad instead
of smpeg that he/she could share.
