[mythtv-users] tmdb3 fails with "No module named MythTV.tmdb3"

[Yan Seiner]

I'm trying to get tmdb3 running, and it fails with:

root at NewMoon:/usr/lib/python2.7/dist-packages# 
/usr/share/mythtv/metadata/Movie/tmdb3.py
Traceback (most recent call last):
   File "/usr/share/mythtv/metadata/Movie/tmdb3.py", line 294, in <module>
     main()
   File "/usr/share/mythtv/metadata/Movie/tmdb3.py", line 265, in main
     from MythTV.tmdb3 import set_key, set_cache, set_locale
ImportError: No module named MythTV.tmdb3

The MythTV modules are installed in

/usr/lib/python2.7/dist-packages/MythTV

so I can't figure out why it's failing.  Likely it's something with 
either distro or local config, but I can't find it....

I am running Ubuntu 12.04 LTS, python 2.7, and Myth 0.27.

Any ideas on where to look?
