I am getting error:

Could not find bundler (>= 0) amongst [aruba-0.4.5, bcat-0.6.1, builder-3.0.0, childprocess-0.2.0, cucumber-1.0.2, diff-lcs-1.1.2, ffi-1.0.9, gherkin-2.4.5, json-1.5.3, rack-1.3.2, rake-0.9.2, rdiscount-1.6.8, rspec-2.6.0, rspec-core-2.6.4, rspec-expectations-2.6.0, rspec-mocks-2.6.0, term-ansicolor-1.0.6] (Gem::LoadError)

I get the error in our app that uses appraisal and I'm getting the error in the appraisal cucumber features. for the appraisal app I run "bundle exec rake cucumber" and get the below failed scenarios with the error above. I am failing on step 'When I successfully run bundle exec rake appraisal:install --trace'

Failing Scenarios:
cucumber features/appraisals.feature:45 # Scenario: run a specific task with one appraisal
cucumber features/gemspec.feature:47 # Scenario: run a gem in the gemspec
cucumber features/gemspec.feature:60 # Scenario: run a gem in the gemspec via path

I vendor my gems to vendor/ruby and I'm the only one at work that does this. everyone else uses gemsets that I'm aware of and they can run the tests fine. I should also mention that I use rbenv and not rvm for my ruby version management although I don't see how that would be the problem.
