title: RVM: Incorrect Ruby version referenced after removal
body: <p>Just updated the version of Ruby (1.9.2 to 1.9.3) I have installed but now getting the following error when running <code>rake</code>:</p>
  
  <pre><code>$ rake
  -bash: /Users/mike.simmonds/.rvm/gems/ruby-1.9.3-p0/bin/rake: /Users/mike.simmonds/.rvm/rubies/ruby-1.9.2-p180/bin/ruby: bad interpreter: No such file or directory
  </code></pre>
