Rails Generate throwing Minitest error?

Question

I am just starting to learn Rails and I'm creating my first project. In my Gemfile i've added:

group :test, :development do
  gem 'turn'
  gem 'rspec-rails'
  gem 'capybara'
  gem 'guard-rspec'
  gem 'growl_notify'
end

And run bundle. All is going fine so far.

I tried running rails g to see if my packages were installed but I was faced with the following error:

GarysMBA:glecto swally_1991$ rails g
gem install minitest
/Library/Ruby/Gems/1.8/gems/turn-0.9.4/lib/turn/minitest.rb:9:in `require': no such file to load -- minitest/unit (LoadError)

    from /Library/Ruby/Gems/1.8/gems/railties-3.2.3/lib/rails/commands.rb:24
    from script/rails:6:in `require'

I have searched my config but I can't find any references to Minitest anywhere? Has anyone came across this problem before? Or can point me in the right direction of fixing it?
