title: Error with bundle install on Rails app
body: <p>I'm trying to install Ruby on Rails on Windows using <a href="http://nlb-creations.com/2013/06/26/installing-ruby-on-rails-and-redmine-with-xampp-on-windows-7/" rel="nofollow noreferrer">this tutorial</a>.</p>
  
  <p>I successfully finished all the steps until step 13:</p>
  
  <blockquote>
    <p>Run <code>bundle install</code> again</p>
  </blockquote>
  
  <p>This is what I'm getting:</p>
