title: After pushng my Rails up to Openshift I get error: "Could not find rake-10.5.0 in any of the sources"
body: <p>I'm trying to set up my Rails app with Mongo.
  After setting the code as described in the Advanced section <a href="https://blog.openshift.com/converting-an-existing-rails-app-to-run-on-openshift/" rel="nofollow">here</a> </p>
  
  <p>I added the mirror source to Gemfile like this</p>
  
  <pre><code>ruby "2.0.0"
  
  source 'http://mirror1.prod.rhcloud.com/mirror/ruby/'
  source 'https://rubygems.org'
  
  
  # Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
  gem 'rails', '4.2.5'
  ...
  </code></pre>
  
  <p>And to Gemfile.lock</p>
  
  <pre><code>GEM
    remote: http://mirror1.prod.rhcloud.com/mirror/ruby/
    remote: https://rubygems.org/
    specs:
      actionmailer (4.2.5)
  </code></pre>
  
  <p>I tried to push the code and getting:</p>
