After adding the demo code to a page, python can't find something it needs

Python Traceback

I think the plugin is installed correctly: # easy_install http://trac-hacks.org/svn/mediawikipluginmacro

And if I comment out the mediawiki.* = enabled part of the trac.ini, trac says that it doesn't know what to do with the mediawiki directive when loading the page, which makes sense.

Is there a specific dependency that this plugin relies on?

Apologies. The trac-hacks server dumped a 500 error when submitting the ticket. Ticket #1807 should be used for this issue.
