When I try to invoke it (CTRL+F), I get this error:

I checked the reference and it's here - https://github.com/textmate/ruby-on-rails-tmbundle/blob/master/Support/bin/jump_to_method_definition.rb#L5
How should I configure ruby to make that bundle work? I would like to use ruby provided by rbenv as it already works nicely with RSpec bundle for me.
