This is the best I could do to try to get you Mac users in the trenches with the rest of us. The installation is rather tricky, especially since I don't have a Mac to test it on. But someone did get it running, so check the description below for how they did it.
I haven't run this myself but I'm told it works:
You can probably manage this much more easily if you are able to use terminal commands. You might even be able to just copy the relevant files to the proper directory this way, and skip a lot of the above steps.
If you have a better method, a better explanation, or can create an installation script that I can distribute, please let me know! Mac users across the globe would be eternally grateful.
