quick question: just now Josh Bloom (whom you'll remember from
Scipy'12) was trying this very command at my urging, as we want to
update our students for the upcoming python bootcamp at Berkeley
(http://register.pythonbootcamp.info), but he got this nasty
traceback:

This is with an EPD downloaded 2 days ago. Any thoughts on what we're
doing wrong?
