title: PyDev: "Unresolved import nltk" When running, pydev imports it
body: <p>I want to get rid of this error message and I want to have the benefits of auto completion and suggestions. PyDev obviously does find nltk, because when running it from inside the IDE it works. Not only from console.</p>
  
  <p>Surely someone needs to know why I got this "unresolved import" error message but on the other way when clicking on "run" it works perfectly well.</p>
