Why is the gem term-ansicolor not found in my path? I have it in the global gemset for 1.9.2

irb3.rb

For the record I was setting up my mac-book, term-ansicolor was already in the '$ gem list' and got the same error when running '$ rspec spec', in my case it was because I wasn't prepending 'bundle exec'. Doh!
