Putting on my OE-guy hat, if we're shipping a host python for some good
reason, it should be as useful as a stock python install on
desktop-or-server-distro-du-jour. I did some quick poking when I first
hit this and it seems the OE one ships with almost nothing for external
modules which made me question why it's even shipped.
