Trying to make my Ruby environment happy under OS X 10.8 Mountain Lion

A few notes. I had:

• installed XCode 2.4 Preview as well as its command line tools (which are found separately in Preferences -> Downloads)
• updated rvm (rvm get latest)

and my issue was:

• system ruby installed every gem with native extensions I threw at it
