Mathew, Going back through my email stack I found your message. Testing on my machine, using mpl and basemap from svn, and using "ipython --pylab", I don't see any error. The code that you show having raised the exception no longer exists--there is no longer any reference to _pylab_helpers--so I think the problem has been solved.
