I confirm, they were internal SDL deps on Linux. Normally you just need:
- libsdl1.2
- libsdl-image1.2
- libsdl-net1.2
- GL (optional)
- libfreetype6
- libvorbis
- libspeex
- libz
and their own dependencies of course

Hum, try to remove -framework Cocoa. I've the feeling that symbol got 
defined twice, both statically in libSDL.a and dynamically in framework 
Coca. Also, are you sure you have the same version of the framework in 
libSDL.a that you are using now? Those are just idea, please keep in 
mind that I'm not at all an OS X specialist. Of course, I would also 
suggest that you google search something like "illegal reference to 
symbol" OSX.
