How do you run that? (Are you sure you run it via Python executable, which points to the same env cherrypy is installed?)

[webknjaz]

run.py:

#! /usr/bin/env python

from cheroot.wsgi import Server as WSGIServer

from yourdjangoapp.wsgi import application

bind_addr = '0.0.0.0', 8080
WSGIServer(bind_addr, application).safe_start()

$ ./run.py
