title: Does compass-rails support Ruby on Rails 4.0?
body: <p>I have clean new Rails 4 app with Gemfile:</p>
  
  <pre><code>#default gems
  gem 'compass-rails'
  gem 'zurb-foundation'
  gem 'thin'
  </code></pre>
  
  <p>with style.scss:</p>
  
  <pre><code>@import "compass";
  @import "foundation/variables";
  $red: rgb(255,0,1);
  $green: rgb(51,153,50);
  $body-bg: #F4F4F4;
  $body-font-color: #7B7B7B;
  $primary-color: #999;
  $secondary-color: #0CC;
  $dark-color: #393939;
  $block-container-border-color: rgb(218,218,218);
  $block-container-shadow-color: rgb(208,208,208);
  // main background
  html{
    background:image-url('bckg.jpg');
  }
  body{
    width:1000px;
    margin:0 auto;
    @include box-shadow(0px 0px 32px -5px #000);
  }
  </code></pre>
  
  <p>And I have this error:</p>
