guard-rspec 4 requires listen ~> 2.0 gem, but some other gem depends on ~> 1.0

[jmuheim]

When guard tries to run rspec, this is the result:

23:15:41 - INFO - Running: spec/controllers/dashboards_controller_spec.rb
/Users/josh/.rvm/gems/ruby-2.0.0-p353@global/gems/bundler-1.3.5/lib/bundler/rubygems_integration.rb:224:in `block in replace_gem': can't activate listen (~> 1.0), already activated listen-2.3.1. Make sure all dependencies are added to Gemfile. (Gem::LoadError)

My gem versions:

guard-rspec (4.1.0)
guard (2.2.4)
listen (~> 2.1)

I have no idea which gem tries to mount listen ~> 1.0, I don't see it in the Gemfile.lock listen anywhere. Can you tell me which gem versions I need to install to get guard-rspec running with guard ~> 4.0 so I can use the cmd: 'xxx' param?

Thanks for help.

@jmuheim I see your comments on rails/spring#194, so I close that one. Thanks!
