on a Mac OSX 10.9.1 client I would like to try out git-annex.

I download the latest Mavericks build, extract from the .dmg and it just does not run. I open the program, one "bounce" on the dock and it is gone, nothing happens.

I sadly do not have another OSX client to try it on. But nothing shows in the Console.app or anything.

Am I missing something?
