Trouble "activating" gem version

I'm taking a coursera intro class on rails and having some trouble with the gems.

When I run rspec on a new rails project I get this error:

/Users/mme/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/bundler-1.11.2/lib/bundler/runtime.rb:34:in `block in setup': 
You have already activated poltergeist 1.9.0, but your Gemfile requires poltergeist 1.6.0. 
Prepending `bundle exec` to your command may solve this. (Gem::LoadError)

According to How to switch between different version of gem installed?, I should be able to use bundle exec [gem]

$ bundle exec poltergeist
bundler: command not found: poltergeist
Install missing gem executables with `bundle install`

That doesn't make sense - I've used poltergeist previously:

$ bundle install | grep poltergeist
Using poltergeist 1.6.0

Does anyone have some advice on how to reconcile this situation?

Try:

bundle exec rspec

the error suggests "Prepending bundle exec to your command" - which literally means adding bundle exec before the rspec command.
