title: Laravel elixir - more specific error messages from gulp
body: <p>I'm receiving the following error when trying to compile the less files for a theme that I purchased that was packaged with less files.  Here's the output I'm seeing:</p>
  
  <pre><code>$ gulp
  [22:53:49] Using gulpfile ~/path/to/gulpfile.js
  [22:53:49] Starting 'default'...
  [22:53:49] Starting 'less'...
  [22:53:49] Running Less: resources/assets/less/style.less
  [22:53:49] Finished 'default' after 524 ms
  [22:53:50] gulp-notify: [Laravel Elixir] Less Compilation Failed!: no writecb in Transform class
  [Error: no writecb in Transform class]
  </code></pre>
  
  <p>How can I obtain a more specific error message?  Googling this error message yielded no useful results.</p>
