Allow Gentoo to manage python versions by itself

Browse Source 
Gentoo can manage python versions itself.  Before this commit users were
forced to set python versions themselves.  Now they have the option to
set it if they wish.

The workaround needed for git is also no longer needed, so it's been
removed.
