Ok, I just wanted to say what exists first. If you consider providing a game for Mac OS X, that will not work on the most recent versions 10.7 and 10.8, an option, read on.
There's a source code repository where you can get the code, compile it and bundle that with your game. Nobody has ever written down how to do that, so you must wait until someone explains it here if you want to do it. I don't know how to do it.
