Preliminary patch for the (new) scipy

I've submitted the following:

This patch allows one to use matplotlib with (just)
the new scipy.

The matplotlib built with this patch and just
the new scipy passes the examples/
test with errors only occuring on those tests which
explicitly includes numarray, and a few others which
i believe are unrelated to the patch.

There are some issues with parallel installation.
I have only tested this with a python installation that
has only the new scipy. In principle, this should be
compatible with a parallel installation of scipy and
numarray, but scipy and Numeric will not work, because
I select to build extensions only for one or the other.
