title: everything working except rails. rails -v returns a long message. Gem::LoadError + other stuff
body: <p>I'm so frustrated. I just wiped my computer clean for a new start, after trying for several days to get rails installed. I followed this tutorial <a href="http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/#step-4" rel="nofollow">http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/#step-4</a></p>
  
  <p>It actually worked too, but when I woke up the next morning, I got this new "error"</p>
  
  <p>Everything seemed to be working. I installed xcode, homebrew first, and then installed RVM. and it all seems to be working. I have ruby 2.0.0, but when I type "rails -v" after installing I get the following:</p>
  
  <pre><code>$ rails -v
