title: Passenger showing index of folder, rather than rendering site with Rails
body: <p>Similar to this question: <a href="https://stackoverflow.com/questions/154959/apache-rails-passenger-displaying-site-index">Apache/Rails/Passenger Displaying Site Index?</a></p>
  
  <p>Only difference is that my app is pointing to the public directory. </p>
  
  <p>Running <code>ps aux | grep rails</code> shows that there is a rails instance running, but it's not rendering my app</p>
  
  <p>Here is my apache2.conf: <a href="http://pastebin.com/twipcruz" rel="nofollow noreferrer">http://pastebin.com/twipcruz</a></p>
  
  <p>One possible problem is that PassengerRoot and PassengerRuby are pointing to different versions, but this block was simply copied and pasted from the <code>passenger-install-apache2-module</code> output</p>
  
  <pre><code>#Passenger Setup
  LoadModule passenger_module /home/john/.rvm/gems/ruby-1.9.2-p318/gems/passenger-3.0.11/ext/apache2/mod_passenger.so
     PassengerRoot /home/john/.rvm/gems/ruby-1.9.2-p318/gems/passenger-3.0.11
     PassengerRuby /usr/bin/ruby1.8
  </code></pre>
  
  <p>getting this from the log:</p>
  
  <pre><code>10:13:24 2012] [error] *** Passenger could not be initialized because of this error: The Passenger spawn server script, '/home/john/.rvm/gems/ruby-1.9.2-p318/gems/passenger-3.0.11/lib/phusion_passenger/passenger-spawn-server', does not exist. Please check whether the 'PassengerRoot' option is specified correctly.
