need to document the dependencies; traceback using python 2.5

There is no documentation I could find.

Most important to start with: a description of the dependencies. (My guess,
based on an error message and traceback: pyglet (which version?), and
either python 2.6 or simplejson.)

BTW, the error message is misleading since it suggests that not installing
those things will only lead to a lack of safety, not to the traceback --
perhaps that's is a separate bug? (The traceback occurs with Python 2.5 and
Pyglet 1.1.3 on a Mac. Kytten is from the svn trunk, revision 24.)

Warning: using 'safe_eval' to process json files, please upgrade to Python
2.6 or install simplejson
