Correct Guardfile definition for Unicorn?

[netwire88]

Hi,
I want to ensure the documentation on using guard rails with Unicorn is correct. I have the following setting in my Guardfile according to the instructions.

guard 'rails', :port => 5003, :environment => 'test', :server => :unicorn, :preloading => true do
  watch('Gemfile.lock')
  watch(%r{^(config|lib)/.*})
end

However, I'm getting this:

22:18:36 - INFO - Guard is using TerminalTitle to send notifications.
22:18:36 - INFO - Guard::RSpec is running
22:18:36 - INFO - [Guard::Rails] will start unicorn on port 5003 in test.
22:18:36 - INFO - Starting Rails...

Any ideas what I'm doing wrong?

Can you check if your unicorn be installed properly?
And what if run rails server with unicorn directly from the shell?
