On two different computers running XP I get:

Perl version: 5.8.8

* C:\Program Files\ActiveState Komodo 3.5\lib\support\dbgp\perllib

Try uninstalling Tk and then reinstalling it.

Note, I wasn't interested in the error message as such, we already had that information. I was more interested in confirming that the include path was sensible before Tk is loaded and trashed afterwards. You haven't actually confirmed that yet.
