If you get it in, and this means (brew, formulas.. and for that matter MacOS are confusing to me) that MacOS users can just install stackless from source with no extra work, let us know and we'll point the downloads page to the appropriate place with a mention.
Wasn't accepted for the master, they wanted it at most keg only, gave up on that for the moment. They mentioned to have a hell of a lot of Python problems on the Mac interfering with the system one, so they were not really enthusiastic about having yet another 'Python'.
Be it as it is, there is still the way to go without forking and simply do a brew create, with a new formula called 'stackless' and paste the attached file into it in full, replacing the presented boilerplate Ruby code and then do a brew install stackless, living with your local formula.
Enjoy, Werner
