cpanminus has plugins branch on git and I have 'git_site_perl' plugin
to exactly do this: whenever you install a new module using cpanminus,
your site_perl (local::lib configured path or $Config{installsitelib})
files will be committed to git for versioning.

This is a rip off of nothingmuch's git-site-perl hook and actually
works well with local::lib while his doesn't.
