Just a small note: The sdl egg is also available as sdl-base, sdl-ttf,
sdl-net, etc. so if you don't need everything you can concentrate on
the parts you actually need. The sdl egg has been left as is for
backwards compatibility.

Thanks for the help guys. I only need sdl-base for now (later on, sdl-ttf will be required) and installing just sdl-base worked (compiled and linked). I am getting a NSInternalConsistencyException now but I recall reading something about it in the documentation.

sdl_net was already linked to /usr/local/lib, so I am not sure what went wrong, I will investigate when I get more free time. My feeling is that there are some missing functions (maybe due to the version I have?), I'll dump the symbols to check.

Also, pkg-config output:

$  pkg-config --libs sdl

-Wl,-framework,Cocoa -L/usr/local/lib -lSDLmain -lSDL
