Well if it's OctaMED you want, just use the PC version. I have it here (though not used it for years there are simply better trackers out there now, not that I use trackers anymore)... But it does work in Wine so it will run on your OSX/*nix boxes too.
LMAROF!
You're not serious. Really. OSS for the PC is a skippy buggy abomination that gives the concept of a "tracker" software a really bad name.
