Awesome I guess we really need a tutorial for new Mac OS X users.
Btw: If you would want or need to compile libSDLmain.a for yourself for i386 and ppc platforms you need to call this line
gcc -c -o SDLMain.o SDLMain.m -I /Library/Frameworks/SDL.framework/Headers
with an additional --arch i386 or --arch ppc parameter depending on which platform you need.
