title: Install omniauth rails 2.3.4
body: <p>I have a rails 2.3.4 app that I'd like to extend with omniauth (0.1.5).  When I install omniauth gem using rvm and place require 'omniauth' in the config.rb file I get the following error: </p>
  
  <p>`gem_original_require': no such file to load -- omniauth (MissingSourceFile)</p>
  
  <p>The tutorials suggest using putting it in the gemfile but I am using rails 2.</p>
  
  <p>When I 'gem list' omniauth is available however.</p>
  
  <p>This has taken a couple of (hair-pulling) days and I am not sure how to proceed. </p>
  
  <p>Am I placing the require in the correct place or is there somewhere else I could put it (aside form the obvious :-))?</p>
  
  <p>Any ideas would be great....</p>
  
  <p><strong>EDIT 1:</strong> I tried config.gem "omniauth" in your environments.rb file and got 
  /home/mcaulejj/explorer/config/environment.rb:10: undefined local variable or method `config' for main:Object (NameError)</p>
  
  <p><strong>EDIT 2:</strong> Using RVM I updated all gems but I am still getting the same error.....</p>
  
  <p>I'm exasperated at this point. </p>
