body: <p>I followed <a href="http://gruntjs.com/getting-started" rel="nofollow">http://gruntjs.com/getting-started</a> to install grunt on my Ubuntu 11.10. When I ran grunt, I got this error:</p>

  <p>I previously used grunt 0.3.16. I am upgrading to the latest grunt. It doesn't seem to be related to my project. I get this error in any directory.</p>
