title: heroku rake db:migrate, rake aborted! undefined method 'task'
body: <p>When i run:
  heroku rake db:migrate,</p>
  
  <p>I get this error message:</p>
  
  <pre><code> rake aborted!
   undefined method 'task' for #&lt;'Myapp::Application:0x7f07c011f4f8&gt;
  </code></pre>
  
  <p>I'm running rake 0.8.7 and have uninstalled rake 0.9.</p>
  
  <p>Also, when i add --trace, these files come up:</p>
  
  <pre><code>/app/.bundle/gems/ruby/1.8/gems/railties-3.0.7/lib/rails/application.rb
  /app/.bundle/gems/ruby/1.8/gems/rake-0.9.0/lib/rake/rake_module.rb
  /app/.bundle/gems/ruby/1.8/gems/rake-0.9.0/lib/rake/application.rb
  </code></pre>
  
  <p>(sorry for not being exact, I can't copy n paste, I'm running windows)</p>
  
  <p>So, im guessin the rake-0.9.0 file that comes up is the culprit :S, but i
  dunno how to deal with it. </p>
  
  <p>Thanks in advance</p>
