Problem with cucumber

Question

I want to make rails app which will require minimum gems. I freeze gems into app and try to run cucumber's test and I've got the an error. Below is sequence of my actions. What I do wrong?

1. rails cucumber && cd cucumber

2. rake rails:freeze:gems

3. add at the end of config/environments/test.rb:

   config.gem 'gherkin'

   config.gem 'cucumber-rails'

   config.gem 'database_cleaner'

   config.gem 'webrat'

4. rake gems:unpack:dependencies RAILS_ENV=test

5. rake gems:build RAILS_ENV=test

6. rake gems RAILS_ENV=test

9. gem uninstall builder cucumber cucumber-rails diff-lcs gherkin json_pure nokogiri rack-test term-ansicolor trollop webrat
