title: No Growl Notifications with Rails Tutorial 3.2
body: <p>Michael Hartl's wonderful <a href="http://ruby.railstutorial.org/" rel="nofollow">Rails Tutorial</a> is now available for Rails 3.2.  He continues to outline TDD and BDD using rspec and spork as he did in version 3.0 and adds guard in 3.2.  In version 3.0, Hartl includes information about autotest and I was able to get the wonderful growl notifications working.  In 3.2, however, he no longer includes autotest or much growl information.  Guard is working nicely with spork but there's no notifications.  I've ventured out on my own the last couple hours using Hartl's 3.0 and some blog posts but trying to get autotest to work still produces a "LoadError" and a growl notification "could not run tests."  Super grateful for any thoughts.  I'm on OS X 10.7.3.  Here's what I did:</p>
  
  <pre><code>$ gem install autotest -v 4.4.6
  $ gem install autotest-rails-pure -v 4.1.2
  $ gem install autotest-fsevent -v 0.2.8
  $ gem install autotest-growl -v 0.2.16
