I just reproduced this error on my Ubuntu machine running ruby 2.1.5.

This is due to the libnotify gem not being installed, I guess because this gem is Linux specific. You can install manually it with gem install libnotify
Needs a platform-specific gemfile to 'fix', but then this means you can't include a Gemfile.lock (which isn't currently included anyway).

Adding to this, I needed to install ruby-dev to install libnotify. Not surprising, but I'm not ruby developer and it took some googling to figure it out.
