Using `source/components` instead of `output_dev/components` seems to result in a syntax error in Twig:

    [Twig_Error_Syntax]                                                          
      Unclosed comment in "FileSource:FilesystemDataSource:/var/www/sculpin.io/so  
      urce:components/modernizr/modernizr.js" at line 457

The line in Modernizr is:
``` javascript
        } else {
          injectElementWithStyles(['@media (',prefixes.join('touch-enabled),('),mod,')','{#modernizr{top:9px;position:absolute}}'].join(''), function( node ) {
            bool = node.offsetTop === 9;
          });
```

Not sure what's wrong with that. Know if we could push a fix forwards?
