I don't think this is CVE worthy, but it is worth fixing and not
putting everyone at such risk:

https://bugzilla.novell.com/show_bug.cgi?id=834785
https://bugzilla.redhat.com/show_bug.cgi?id=997179

Problem #1:
install /etc/gemrc to install gems via https rather than http

everyone should be enabling HTTPS where possible, intercepting and
modifying HTTP is trivial.

Problem #2:
it redirects to  production.cf.rubygems.org which is on cloudfront so
has certificate mismatch, so either users have to accept insecurity,
or... well there is no second choice =(.

pip has a CVE for downloading via HTTP, does switching the
gem to HTTPS actually make gem verify it?
