title: RoR burke's zeus gem gives exit status 1 when using Ubuntu 13.04
body: <p>The Zeus gem <a href="https://github.com/burke/zeus" rel="nofollow">https://github.com/burke/zeus</a> works as expected on MacOSX, however, on a Linux box it exhibits the issues described (and unresolved) here: <a href="https://github.com/burke/zeus/issues/237" rel="nofollow">https://github.com/burke/zeus/issues/237</a></p>
  
  <p>Using:</p>
  
  <ul>
  <li>Rbenv with ruby 1.9.3-p327-perf</li>
  <li>Ubuntu 13.04</li>
  <li>golang version 2:1.0.2-2 (according to "dpkg -l")</li>
  <li>Tried several zeus releases</li>
  </ul>
  
  <hr>
  
  <h2>Problem</h2>
  
  <p>Terminal: "zeus start" gives "exit status 1" briefly, then the colourful terminal interface shifts down one line and it hangs, all lines "waiting" (coloured yellow).</p>
  
  <hr>
  
  <h2>Troubleshooting so far</h2>
  
  <p>Terminal:</p>
  
  <pre><code>sudo apt-get install golang
  </code></pre>
  
  <p>(On MacOSX it was "brew install go")</p>
  
  <pre><code>gem install zeus -v 0.13.3.rc2 --pre
  </code></pre>
  
  <p>(Have also tried "gem install zeus -v 0.13.3.rc2" and "gem install zeus" with a gem uninstall and recreation of initialisation files zeus.json and custom_plan.rb each time)</p>
  
  <pre><code>gem list
  </code></pre>
  
  <p>(One version of Zeus installed)</p>
  
  <pre><code>bundle show
  </code></pre>
  
  <p>(Zeus not bundled, as expected)</p>
  
  <pre><code>zeus init
  </code></pre>
  
  <p>(Also tried alternatively removing zeus.json and custom_plan.rb)</p>
  
  <hr>
  
  <h2>Update</h2>
  
  <p>Also not working on MacOSX on colleague's machine:</p>
  
  <pre><code>&gt; sudo brew install go
  Warning: go-1.0.3 already installed
  
  &gt; gem list
  *** LOCAL GEMS ***
  method_source (0.8.1)
  zeus (0.13.3)
  
  &gt; rbenv version
  1.9.3-p327-perf
  </code></pre>
  
  <h2>Update2</h2>
  
  <p>Ok so I have ssh access to a Linux box (Ubuntu) which has got Zeus working on it with the same codebase. What diagnostics can I use to determine/compare what it has different to my local machine? I'm looking into dpkg --get-selections for now</p>
  
  <h2>Update3</h2>
  
  <pre><code>gem list
  </code></pre>
  
  <p>was showing the installed json version (1.5.4).</p>
  
  <pre><code>bundle show
  </code></pre>
  
  <p>was showing the installed json version (1.7.7).</p>
  
  <p>An update on the issue here <a href="https://github.com/burke/zeus/issues/237" rel="nofollow">https://github.com/burke/zeus/issues/237</a> suggests that json version could be the problem; given that zeus is installed with the ruby version and not with the gemfile (it shows under gem list) I ran:</p>
  
  <pre><code>gem install json --version 1.7.7
  gem uninstall json --version 1.5.4
  rm zeus.json
  rm custom_plan.rb
  zeus init
  zeus start
  </code></pre>
  
  <p>However this does not fix the problem for me, and on the mac where it is failing, Json 1.7.7 is installed.</p>
