title: Grunt Sass Error: File to import not found or unreadable
body: <p>This works locally but when I grunt on my ubuntu I  get this sass error. I have ruby and sass installed, grunt as well</p>
  
  <pre><code>Running "sass:dist" (sass) task
  Error: File to import not found or unreadable: /public/libs/bootswatch-scss/cyborg/variables.
         Load path: /opt/app/soundapp/public/style/sass
          on line 1 of public/style/sass/style.scss
    Use --trace for backtrace.
  File "public/builds/style.css" created.
  </code></pre>
  
  <p>As the error shows I use grunt to run my stuff. Here's the top of my style.scss</p>
  
  <pre><code>@import "public/libs/bootswatch-scss/cyborg/variables";
  @import "public/libs/bootstrap-sass-official/assets/stylesheets/bootstrap/variables";

  <p>How can I begin to debug this? All the files in my public/libs/ exist so it has to be a compiling issue not related to it finding the files? I have Sass 3.4.13 and ruby 1.9.3p484 installed</p>
