Missing these required gems:
  selenium-client
  Selenium
  rspec-rails
  test-unit

You're running:
  ruby 1.9.1.378 at /home/artem/.rvm/rubies/ruby-1.9.1-p378/bin/ruby
  rubygems 1.3.5 at /home/artem/.rvm/gems/ruby-1.9.1-p378, /home/artem/.rvm/gems/ruby-1.9.1-p378%global

All gems are obviously there:

artem:~/projects/food4feed (master)$ gem list | egrep "elenium|rspec|test-unit"
rspec (1.3.0)
rspec-rails (1.3.2)
Selenium (1.1.14)
selenium-client (1.2.18)
test-unit (2.0.7)

The even more confusing part is that it only complains about certain gems. factory_girl and rspec don't cause problems.

Any idea what is going on?

My environment:

• Rails 2.3.5
• cucumber (0.6.3)
• cucumber-rails (0.3.0)
