### Please describe the problem.

When trying to create a repository—i.e., running it for the first time—I get this error message:

> user error (git ["--git-dir=(path)/.git","--work-tree=(path)","commit-tree","4b825dc642cb6eb9a060e54bf8d69288fbee4904","--no-gpg-sign"] exited 128)

It _seems_ that it's because the bundled `git` executable isn't used, and instead `/usr/bin/git` is; and it's too old to support the `--no-gpg-sign` flag.


### What steps will reproduce the problem?

Run `git-annex.app` for the first time and give it a path.


### What version of git-annex are you using? On what operating system?

    $ /Applications/Git-Annex.app/Contents/MacOS/git-annex version
    git-annex version: 5.20140707-gf0c48e8
