I actually am installing it in a quite vanilla way.

I think our installation procedure places Git.pm in git specific
perl library path where a simple invocation of "perl" that is
git-unaware will not look into, and we make sure that our scripts
still find the matching version of Git.pm by having "use lib" at the
beginning that points at the right directory.

But of course, this from a command line would not work:

	$ perl -MGit

I do not expect it to, and for the ease of testing new versions, I
prefer it not to work.

In any case, you should be able to do anything under t/ _before_
installing, so relying on having Git.pm in normal @INC is a double
no-no.
