Rspec: `should': uninitialized constant RSpec::Expectations (NameError)

Hi all, tried posting this to rspec group but w/o success so hope someone on this list might be able to help me out as am kind of stuck:

Can anyone tell me why I am getting this error trying to ‘rake spec’:

‘kernel.rb:27:in `should’: uninitialized constant RSpec::Expectations (NameError)'.

Can’t seem to find a useful reference online to solve. This project I was working on a few months ago and got put aside, meanwhile I rebuilt my mac. So something is off but not sure what.

Using rvm, Rails 3.0.3, Ruby 1.9.2, my gemfile.lock installs fine and shows the following for rspec. I actually deleted my rvm gemset and re-installed the bundle just in case but same error.

Gemfile.lock rspec (2.2.0) rspec-core (~> 2.2) rspec-expectations (~> 2.2) rspec-mocks (~> 2.2) rspec-core (2.2.1) rspec-expectations (2.2.0) diff-lcs (~> 1.1.2) rspec-mocks (2.2.0) rspec-rails (2.2.1) actionpack (~> 3.0) activesupport (~> 3.0) railties (~> 3.0) rspec (~> 2.2.0)

Gemfile:

group :development, :test do gem ‘ruby-debug19’ gem ‘cucumber-rails’ gem ‘cucumber’, ‘>=0.8.5’ gem ‘capybara’ gem ‘rspec-rails’ gem ‘factory_girl_rails’ gem ‘webrat’, ‘>=0.4.3’ gem ‘heroku’ gem ‘database_cleaner’ end

Thanks,

David
