Compiling issue with relative path name

I had an issue with "rake db:run" that begins:
ActionView::Template::Error: require_tree argument must be a relative path
  (in /home/max/Code/potlucky/spec/javascripts/spec_helper.js.coffee:5)
This change resolved that issue for me. Thanks for the great project!
