matplotlib does not require numpy or scipy to build or run. You can
simply set 'numerix : Numeric' or 'numerix : numarray' in your rc file
and still use the same old libs you want.
So feel free to update to the latest version if you want. I will look
into the figimage problem later.

Hi John,
I've found the source of this figimage problem.
In _backend_agg.cpp RendererAgg::draw_image is expecting 4 arguments and is being passed 5 by the FigureImage draw method in image.py
The offending line is:
renderer.draw_image(self.ox, self.oy, im, self.origin, self.figure.bbox)
Changing this to
renderer.draw_image(self.ox, self.oy, im, self.figure.bbox)
solved the problem for me.
I checked and found that the RendererAgg draw_image() virtual method has 5 arguments, which seems to be the source of the problem, so either this needs changing or the backend code does.
_draw_image() in backend_agg.py makes the call with 3 arguments, so this needs fixing too.
The draw_image() method in backend_emf.py has a stub override with 5 arguments, so this may need changing too, although it isn't causing harm yet. I'm not sure all of these are real problems because I didn't try too hard to understand how the backends work.
regards,
Gary R.
