title: compass-rails gem not being run in heroku?
body: <p>My gemfile recently upgraded my compass-rails gem. I started getting the following error (production on heroku only - works fine locally), and have been stuck on it for hours:</p>
  
  <pre><code>Completed 500 Internal Server Error in 14284ms
  2012-09-03T20:53:25+00:00 app[web.1]: 
  2012-09-03T20:53:25+00:00 app[web.1]: ActionView::Template::Error (File to import not found or unreadable: compass/css3.
  2012-09-03T20:53:25+00:00 app[web.1]: Load path: Sass::Rails::Importer(/app/app/assets/stylesheets/application.css.scss)
  </code></pre>
  
  <p>I think part of the problem must lie within the fact the /app/app/ is appearing in the path here - but I dont understand why. When I change the compass config below, to "assets/stylesheets" I still see /app/app/ in the trace error.</p>
  
  <p>production.rb:</p>
  
  <pre><code>  # Don't fallback to assets pipeline if a precompiled asset is missed
    config.assets.compile = false
  </code></pre>
  
  <p>compass.rb</p>
  
  <pre><code># Require any additional compass plugins here.
  project_type = :rails
  sass_dir = "app/assets/stylesheets"
  </code></pre>
  
  <p>Gemfile</p>
  
  <pre><code>group :assets do
    gem 'sass-rails'
    gem 'coffee-rails'
    gem 'uglifier', '1.2.4'
    gem 'yui-compressor', '0.9.6'
    gem 'compass-rails'
  end
  </code></pre>
  
  <p>In my application.css.scss file:</p>
  
  <pre><code>@import "compass/css3";
  </code></pre>
  
  <p>I've been trying every solution I can find without any luck so far</p>
  
  <p>Anything sticking out?</p>
