I got curious this morning and wanted to try out the QtAgg backend. I get the
following error when I try to import pylab from a python interpreter:
line 12, in ?
from backend_qt import qt, FigureManagerQT, FigureCanvasQT,\
ImportError: No module named backend_qt
backend_qt.py is present in my cvs directory, but it looks like it didnt make
it into the MPL-0.72 tarball.
