title: Problems with ruby version when bundle install
body: <p>If I give Bundle install I get</p>
  
  <pre><code>Gem::InstallError: factory_girl requires Ruby version &gt;= 1.9.2.
  </code></pre>
  
  <p>But if I do ruby -v I get </p>
  
  <pre><code>ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.2.0]
  </code></pre>
  
  <p>So the problem should be in rails or in bundle that uses the previous version of it, how can I fix it?</p>
