 I had thought that C based gems didn't work at all with MacRuby 1.0.  But
 Matt suggested I make a ticket on this issue.  I'm having an issue where I
 need named expression groups to work with my regexps, this doesn't work
 within MacRuby so I've tried to install RE2, but that doesn't work either:

 sudo macgem install re2
