version 0.63 on windows

When importing this version I find a dependency on PyTz and

This was a bug in the creation of the windows installer, which should
have included these packages. Grab matplotlib-0.63.1.win32-py2.3.exe
from sf, which was just updated minutes ago after someone alerted me
to this problem off-list.

Sorry for the troubles,
