Attempt to fix travis error on 1.8.7/1.9.2: $ bundle install --path vendor/bundle ERROR: Gem bundler is not installed, run `gem install bundler` first. The command "bundle install --path vendor/bundle" failed and exited with 127 during install.
This reverts commit 8a6acc1.
…ss after a string of failures
Don't install ruby-debug if running the test suite on Travis, linecache19 is the main offender, very very slow. And do not install pg if Travis is bundling the gems, pg will be setup on Travis soon.
