Hi,

I'm using thumbs_up for my app but I can't push to Heroku, it says:

```ruby
Installing thumbs_up (0.5.0) Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks!

I'm using `Cedar` stack.

This is my local environment:
- Ruby 1.9.3-p69
- Rails 3.2.1
- RVM 1.6.2
- thumbs_up 0.5.0

I found [this one](http://stackoverflow.com/questions/7130669/heroku-zentest-and-rubygems) and [this one](http://stackoverflow.com/questions/5766140/getting-error-update-rubygems-while-deploying-migrating-to-heroku) but I think they are just workaround, I need thumbs_up in production.

Any idea? Thanks!
