There was a reply of me asking what Homebrew bug is, now I've encountered the problem. It seems to differ from machine by machine - mine works fine doing install/doctor/update/upgrade, while my friend's prompts to upgrade Leopard or higher, which is now resolved by doing brew update. Many formulas seem to be broken now, I guess it'll take some time... github.com/Homebre... cc/ @jackivan88
