Nope, it's the right version being tested.  The failure seems due to your git_version change not liking our formatting

$ git --version
git version 2.10.1 (Apple Git-99)

(the 'Apple Git-XX' being added because this was from a build that had Apple's patch series, including https://github.com/jeremyhu/git/commit/f99905d0752d923e5ec61e14c675a300c6d04284)

We modify DEF_VER, which confused your regex.  Simple patch inc in a separate email.

Thanks,
Jeremy
