Estou com um problema ao usar Bundler e Pepino com o Rails 3.

Quando eu corro$ rake cucumber Eu recebo a seguinte saída:

bundle exec /usr/local/bin/ruby -I "/usr/local/lib/ruby/gems/1.9.1/gems/cucumber-
0.8.5/lib:lib" "/usr/local/lib/ruby/gems/1.9.1/gems/cucumber-0.8.5/bin/cucumber"  --profile default
(in /home/<username>/practice/rails/blog)
Using the default profile...
UUUU

1 scenario (1 undefined)
4 steps (4 undefined)
0m1.552s

You can implement step definitions for undefined steps with these snippets:

Given /^a post$/ do
  pending # express the regexp above with the code you wish you had
end

Given /^a name was specified$/ do
  pending # express the regexp above with the code you wish you had
end

When /^I save the post$/ do
  pending # express the regexp above with the code you wish you had
end

Then /^the post should be saving$/ do
  pending # express the regexp above with the code you wish you had
end

Apesar dessa saída, meus recursos funcionam bem e, quando adiciono definições de etapas e as passo a passar, todas as alterações são exibidas no console corretamente.

Aqui está o meu Gemfile:

group :development, :test do
  gem 'cucumber-rails'
  gem 'rspec-rails', '>= 2.0.0.beta.22'
  gem 'Selenium'
  gem 'thin'
  gem 'webrat'
end

Quero observar, se eu usar obundle exec cucumber oucucumber features/ comandos Não recebo nenhuma mensagem de erro.

Qual o motivo desse problema? Como posso resolver isso?

Obrigado.
