rspec users - Nov 2010 - rspec and autotest integration problem

Hi all,

i am new to ruby and rails and i am following the tutorial in 
http://railstutorial.org/chapters/static-pages#sec:autotest
railstutorial.org  to setup the rspec and autotest in my Ubuntu 10.04

i have the following gems installed

rspec (2.0.1)
rspec-core (2.0.1)
rspec-expectations (2.0.1)
rspec-mocks (2.0.1)
rspec-rails (2.0.1)
test-unit (2.1.1)
redgreen (1.2.2)
ZenTest (4.4.0)
autotest-rails-pure (4.1.0)
autotest (4.4.2)


i also have libnotify-bin installed in my Ubuntu 10.04. as well as adding
?require ?test/unit/ui/console/testrunner?? in my .autotest file.

i have tested the notify-send command and it works well and i run the test
case with ?rspec spec? without any problem.

but when i run autotest. there is not popup in my ubuntu gnome. and when i
quit the autotest by ^C^C. the following error is shown.

ykyuen at ykyuen-laptop:~/Documents/RailsApplications/sample_app$ autotest

...


and this is my .autotest.

#!/bin/ruby
require ''test/unit/ui/console/testrunner''
require ''redgreen''
#require ''test_notifier/runner/autotest''
require ''autotest/timestamp''

module Autotest::GnomeNotify
  def self.notify title, msg, img
    system "notify-send ''#{title}''
''#{msg}'' -i #{img} -t 3000"
  end

  Autotest.add_hook :ran_command do |at|
    image_root = "~/.autotest_images"
    results = [at.results].flatten.join("\n")
    results.gsub!(/\\e\[\d+m/,'''')
    output
results.slice(/(\d+)\sexamples?,\s(\d+)\sfailures?(,\s(\d+)\spending?|)/)
    full_sentence, green, failures, garbage, pending = $~.to_a.map(&:to_i)
    if output
      if failures > 0
        notify "FAIL", "#{output}",
"#{image_root}/fail.png"
      elsif pending > 0
        notify "Pending", "#{output}",
"#{image_root}/pending.png"
      else
        notify "Pass", "#{output}",
"#{image_root}/pass.png"
      end
    end
  end
end


Have i missed anything? Thanks.
