Web2py & Google App Engine import errors

I tried to start web2py 1.98.1 using dev_appserver.py, but it cannot find the "pickle" module.

Traceback (most recent call last): File "/home/matthew/dev/sdks/google_appengine_1.5.2/google/appengine/ tools/dev_appserver.py", line 4144, in _HandleRequest self._Dispatch(dispatcher, self.rfile, outfile, env_dict)

When I import it using the interpreter, it imports without error. Is there a path I have to include somewhere?
