Start by reproducing the styles:compass task in gulp-compass and inspect the reported RubyGems stack trace, especially the gulp-compass plugin entry point. Determine whether the failure is caused by the plugin or the Ruby/Compass environment; done means the task completes without the Compass failed error.
