title: pow says: Bundler::GemNotFound: Could not find rake-0.9.2.2 in any of the sources
body: <p>I have a rails app that runs fine with <code>rails s</code>, but when I try to load it using pow I'm getting this error:</p>
  
  <pre><code>Bundler::GemNotFound: Could not find rake-0.9.2.2 in any of the sources
  ~/.rvm/gems/ruby-1.9.2-p290/gems/bundler-1.0.22/lib/bundler/spec_set.rb:88:in `block in materialize'
  ~/.rvm/gems/ruby-1.9.2-p290/gems/bundler-1.0.22/lib/bundler/spec_set.rb:82:in `map!'
  ~/.rvm/gems/ruby-1.9.2-p290/gems/bundler-1.0.22/lib/bundler/spec_set.rb:82:in `materialize'
  ....
  </code></pre>
  
  <p>Weird thing is, the .rvmrc file in this app specifies <code>1.9.3-p125</code>:</p>
  
  <pre><code>which rake
  .../.rvm/gems/ruby-1.9.3-p125/bin/rake
  </code></pre>
  
  <p>and here's what I see when I run <code>bundle install</code>:</p>
  
  <pre><code>Using rake (0.9.2.2) 
  </code></pre>
  
  <p>FWIW, pow works just fine with another non-rails project using 1.9.2 and a different gemset.</p>
  
  <p>Thanks!</p>
