title: Rake aborted: Don't know how to build task 'jobs:work'
body: <p>When I run <code>bundle exec rake jobs:work</code> I receive this error:</p>
  
  <pre><code>rake aborted!
  Don't know how to build task 'jobs:work'
  </code></pre>
  
  <p>Anything wrong with the syntax?</p>
  
  <p>Note: I installed delayed_jobs like this:</p>
  
  <pre><code>rails plugin install git://github.com/collectiveidea/delayed_job.git
  rails generate migration create_delayed_jobs
  [ Fill the migration from https://github.com/collectiveidea/delayed_job ]
  bundle exec rake db:migrate
  </code></pre>
