You may need to adjust the following...

The PYTHONPATH environment variable so that moin can find the right libraries. 
You seem to have Moin in /usr/local, so this may not be an issue.

The --config-dir option to the moin program. This usually needs setting to the 
path where your wikiconfig.py file is found.

The --wiki-url option to the moin program. This seems to be important when 
dealing with wikifarms where multiple wikis are available, but it is also 
possible that some operations need URL information.

The privileges used to run the command. Some operations won't work if moin 
encounters files it cannot update with the privileges it has.

In the traceback, I see some references to the dreaded caching system:

I always get worried about this because you can get some very difficult-to-
follow errors when the cache mechanism isn't working for some reason. However, 
I think it may be the following request-related operations which fail:

I would start with setting --config-dir and see what error you get next.
