My favorite hack is to build SDL from source, but manually link it. 
Add/replace the -install_name linker command with:

    -install_name @executable_path/libSDL-1.2.0.dylib

Link your program against that library. It will look for it in the same 
directory as the binary at runtime (so copy it into 
XXX.app/Contents/MacOS with your binary).

This isn't really "the Mac way", but it's much more comfortable and 
obvious to my Linux background.
