title: Error when updating my Ruby version using RVM on Mac OS X 10.6.6
body: <p>I tried to update Ruby in my Mac OS X 10.6.6 system. Now I have 1.8.7, and I want to update to 1.9.2.
  When I typed <code>rvm install 1.9.2</code> I got:</p>
  
  <pre><code>gal-harths-iMac:~ galharth$ rvm install 1.9.2
  /Users/galharth/.rvm/rubies/ruby-1.9.2-p136, this may take a while depending on your cpu(s)...
