[web2py] "No module named pickle" when started in App Engine

[Matthew]

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/

    self._Dispatch(dispatcher, self.rfile, outfile, env_dict)

  File "/home/matthew/dev/projects/poprop_cameron/project/src/
gaehandler.py", line 33, in <module>
    import pickle
ImportError: No module named pickle

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

Thanks,
Matthew
