In order to use NLTK 3.0 instead of 2.0, code rewritting will be necessary because item "synsets" have become functions instead of objects. Also note that Heroku latest Stack Cedar-14 used setuptools version 11 which is not comptatible with NLTK 2.0.4. This has been solved in the NLTK 2.0.5 package.
