Joe's Gemfile hashrocket bug fix

I had this same issue this morning. I was able to fix it by deleting all my gems, and then running bundle config path 'vendor/bundle' so it installs the gems inside your app directory (since rbenv has no gemsets), bundle install again, a quick rbenv rehash, and then everything seemed to work again with the newer syntax. I think rbenv for some reason was running my powder gem out of another ruby version and not the current one. I do admit, it was a pretty weird issue, but I was able to get it working.
