  <p>Any ideas or direction on how to about resolving this will much appreciated.If I am missing a file or gem, or if it is a version conflict, it is not clear which one is it.</p>
  
  <p>Also given the different versions on the same gem installed, how could I start the rails app on mongrel specifying exactly what versions I want to use?</p>
  
  <p>Thanks!</p>
