Python Module with FreeRADIUS 3.0.15

Trying to implement just the basic Python example as documented is not working with the FreeRADIUS 3.0.15 build on Unbuntu 14.04. After enabling and running "freeradius -X", FreeRADIUS exits with only this: # Instantiating module "python" from file /etc/freeradius/mods-enabled/python Python version: 2.7.6 (default, Oct 26 2016, 20:33:43) [GCC 4.8.4] Other than enabling the the python module, the only other change was to enable the python_path and uncomment the "func_authorize = authorize" line in mods-available/python. The example.pyc is not created. Everything was working swimmingly under FreeRADIUS 3.0.12. Any ideas? Thanks, Gary
