title: Passenger can't find bundler
body: <p>I am desperatly trying to set up Redmine on my debian server. I managed almost everything (the interface works with webrick), but I want it to be accessable via dev.kaleydra.de, I wanted to solve this by using passenger+the apache2 module.<br>
  So now my current status is this message when I visit dev.kaleydra.de</p>
  
  <p>Error message:
  Redmine requires Bundler. Please install it with <code>gem install bundler</code>.</p>
  
  <p>But bundler is definitly installed! (bundle install worked perfectly)</p>
  
  <p>Some information:  </p>
  
  <pre><code> gem environment
  RubyGems Environment:

  <p>I tried adding this to the enviroment.rb:</p>
  
  <pre><code>ENV['GEM_HOME']='/usr/local/lib/ruby/gems/1.9.1'
  ENV['GEM_PATH']='/usr/local/lib/ruby/gems/1.9.1'
  </code></pre>
  
  <p>What I might notice is that I can't run 
  passenger-install-apache2-module
  because it won't let me install libpq5 (Plesk uses a newer version and it specificly requests "libpq5 (= 8.4.13-0squeeze1)" with apt-get), but since passenger is showing the page makes it look like it already works...</p>
  
  <p>I am kind of desperate, any clues?</p>
