title: Warbler not including gems
body: <p>I'm having a problem where Warbler is not packaging up a few gems.  The gems are:</p>
  
  <p>'prawn 0.11.1' - <a href="https://github.com/sandal/prawn" rel="nofollow">https://github.com/sandal/prawn</a><br />
  'prawnto 0.0.4' - <a href="https://github.com/jlsync/prawnto" rel="nofollow">https://github.com/jlsync/prawnto</a><br />
  'ttfunk 1.0.1'<br /></p>
  
  <p>I'm running Rails 3.0.5, JRuby 1.6.0 and Warbler 1.2.1.  I've tried to tell Warbler to include these gems in the warble.rb config file but that hasn't worked either.</p>
  
  <p>Any ideas?</p>
