RSpec + Autotest Error on Mac OS X

I'm trying to run the command 'bundle exec autotest' in Terminal. I can get RSpec working if I use 'bundle exec rspec spec/', but I can't get autotest (the first command) running. Unfortunately, I get the following error:

Trenton-Scotts-MacBook-Air:sample_app TTS$ bundle exec autotestloading autotest/rails_rspec2

I have two lines in .autotest in my Rails project folder:

require 'autotest/growl'
require 'autotest/fsevent'

I installed the gems for autotest-growl and autotest-fsevent. My Gemfile looks like this:

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'sqlite3-ruby', :require => 'sqlite3'

group :development do
  gem 'autotest'
  gem 'rspec-rails', '2.4.1'
end

group :test do
  gem 'rspec', '2.4.0'
  gem 'webrat', '0.7.1'
end

Any thoughts on how to fix this?

Fixed it! The correct command is 'autotest', not 'bundle exec autotest'. 'rspec spec/' also works too.

Trenton I solved that issue putting all gems executables under /bin with bundle install --binstubs and including growl on Gemfile. I don't know why autotest gem did not created any executable after execute gem install autotest. In which directory do you have that executable?
