title: Sass undefined variable on precompilation
body: <p>I'm upgrading our Rails (3.2.17) app over to sass and I'm running into "undefined variable" errors during asset precompilation. I use @import to include my snippets in the master.scss file. This setup works great locally, but errors on precompliation. The only way to get around the errors is to @import snippets into snippets which reference the mixins and variables defined in the first snippet.</p>
  
  <p>For example: I @import 'fonts' and 'buttons' into master.scss and then I have to @import 'fonts' a second time into 'buttons' because it uses a variable defined in 'fonts'. This gets around the precompliation error, but it's not ideal because instead of only one instance of 'fonts' being loaded into the app, there is now two. </p>
  
  <p>@importing all the snippets only the one time into master.scss works locally when I don't precompile. There has to be a solution to this. Any thoughts?</p>
