Trouble using python module in web2py

Question

I am trying to use a python module (nltk) in web2py.

I am able to use the module from the python command line without issues. In Web2py I get the error below.

Thanks!

Simple example Code:

import nltk
from nltk.corpus import wordnet as wn

def get_thes():
    wn.synset('car.n.01').lemma_names
    return dict()

Error

web2py™ Version 2.5.1-stable+timestamp.2013.06.06.15.39.19

Only the source version of web2py is able to import modules.

Make sure you are not using a compiled version.
