I heard about 0 A.D. a few months ago and thought I would try making a proper Mac build of it (I'm the Mac packager for Wesnoth and Frogatto). I did try to start doing it, but I came upon daunting obstacles and gave up for the time being. I'm still confident that I could do it, and I still hope to eventually if no one else does, but it seemed like a lot of work getting all those libraries working, and I'm kinda busy. Anyway, good luck with the project, it looks like it's coming along nicely!
