That installed etsconfig, util, and traits. I can import traits, but when I
run John Hunters mpl1.py script, I get messages like:

It was suggested here:

I think the problem lies in traits.ui, which is looking for
enthought.resource, which requires pyface.

I'm looking forward to working more with traits, so this is great news. I
think the same traits.ui issue may be preventing us from using traits3, since
enthought.resource does not exist in the trunk.
