title: unable to load grunt-contrib module
body: <p>I am using yeoman for my development workflow. I have installed grunt-contrib in my project folder, and added the loadnpm tasks in my gruntfile.js</p>
  
  <p>However when I start my yeoman server, it keeps giving me the error that local npm module grunt-contrib not found. </p>
  
  <p>I have even tried giving the absolute path to the module, to no avail. Below is the absolute path, is anything wrong with it ?</p>
  
  <pre><code>grunt.loadNpmTasks('/home/murtaza/workspace/yeoman/angular/node_modules/grunt-contrib');
  </code></pre>
