Upgrading Shoulda gem leads to errors with RSpec and Ruby on Rails

Question

After I upgraded my shoulda gem to 3.4.0, my tests would no longer run.

Context:

• Ruby 1.9.3-p392
• Rails 3.2.12
• Rspec 2.13.0 Mac
• OS X 10.8.3

When I set up my Gemfile and run bundle exec rspec spec I get the following errors:

#Gemfile #1
group :test do
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda', '3.4.0'
end

Error: gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- rspec (LoadError)

#Gemfile #2
group :test do
  gem 'factory_girl_rails', '4.2.1'
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda-matchers', '1.5.0'
end

Error: gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- rspec (LoadError)

#Gemfile #3 
group :test do
  gem 'factory_girl_rails', '4.2.1' 
  gem 'rspec', '2.13.0'
  gem 'shoulda', '3.4.0'
end

Error: /gems/activesupport-3.2.13/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- rspec/rails (LoadError)

These are the only Gemfile versions that work, but they don't seem to be the correct setup:

#Gemfile #4
group :test do
  gem 'factory_girl_rails', '4.2.1'
  gem 'rspec', '2.13.0'
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda-matchers', '1.5.0'
end

#Gemfile #5
group :test do
  gem 'factory_girl_rails', '4.2.1'
  gem 'rspec', '2.13.0'
  gem 'rspec-rails', '2.13.0'
  gem 'shoulda', '3.4.0'
end

Upgrade shoulda-matchers to 1.5.4 and change the gem group to development and test

There was a regression in the 1.5.X to 1.5.4. I was having the same issue.
