title: configurable.rb:30:in `method_missing': undefined method `development' for rails app
body: <p>I'm new to rails running Ruby 1.9.2 on an OSX machine and at when I moved to using Thin I get the following error (it's worth mentioning that i've used the gemset on a completely new rails app and it works so I know its something to do with the code or configuration i've written</p>
  
  <p>In terms of the gems I have installed:</p>
  
  <pre><code>gem 'rails', '3.2.3'
  
  # Bundle edge Rails instead:
  # gem 'rails', :git =&gt; 'git://github.com/rails/rails.git'
  gem 'thin'
  gem 'pg'
  gem 'tire'
  gem 'newrelic_rpm'
  gem 'devise'
  </code></pre>
  
  <p>This is the error that I get when running 'rails c'</p>
