How do I get autotest to work?

For the life of me, I can't get autotest to work. I should note that
I am not using RVM, because I couldn't get it to work. I'm doing my
development in VirtualBox so I can seamlessly switch from one setup to
another.

I'm going through chapter 3 at railstutorial.org (http://
ruby.railstutorial.org/chapters/static-pages#sec:first_tests), and I
can't get autotest to work.

As the instructions say, I gem installed autotest -v 4.4.6, autotest-
rails-pure -v 4.1.2, ZenTest, and redgreen and git removed spec/views
and spec/helpers. I used apt-get to install libnotify-bin.

I created the ~/.autotest file and downloaded the images to
~/.autotest_images as instructed at
http://automate-everything.com/2009/08/gnome-and-autospec-notifications/
.

But no matter what I do, entering "bundle exec rspec spec/" gives me a
LONG error message:

CONTENTS OF pages_controller_spec.rb:

Not really an answer to your question, but did you thought about using
guard to get similar behaviour? Additionaly you could use guard-rails to
automatically restart the server when ever it is needed.

You can get guard itself from github:
<https://github.com/guard/guard>

Also there is a growing list of guardscripts:
<https://github.com/guard/guard/wiki/List-of-available-Guards>

A list of scripts I often use:
guard-rails:
  <https://github.com/guard/guard/wiki/List-of-available-Guards>
guard-rspec:
  <https://github.com/guard/guard-rspec>
guard-cucumber:
  <https://github.com/guard/guard-cucumber>

But probably you'll find your own combination of scripts in the list above?

Only thing I miss, would be conditional running of other guards.
Actually it restarts the server if corresponding files where changed,
independent from the outcome of guard-cucumber and guard-rspec.

Do you have spec/spec_helper.rb?
