Hi Howard,

Sorry for the late reply.

Thanks for picking this up.

Guessing from my build directory, it can have been as simple as "python
setup.py build" and "python setup.py install" and then tarring up what got
installed into apps/Python27/lib/site-packages.

It needs the VS 2008 compiler (MSVC 15, I think), which is also what is used
for QGIS, so that would have been in place already.

Not sure.  The tests in numpy require `nose`, which we didn't and apparently
still don't have.

Dependants are gdal-python, GRASS, matplotlib and pyqwt5-qt4.  matplotlib in
turn is used by GRASS and QGIS and pyqwt5-qt4 just by QGIS.  For QGIS the
dependencies are just there to support plugins.

I think matplotlib would also need to be updated/rebuilt to work with a newer
numpy.  The numpy dependency in pyqwt5 is optional.

Not sure if there's anything to be done for GRASS or gdal-python - but I
suppose both will hopefully be updated soon anyway (when GDAL 1.10 and GRASS
6.4.3 are released).
