This may be more FUD than fact but... my recollection of this is that
different versions of Tcl/Tk are used between Python-2.2 and
Python-2.3,  I believe 8.3 and 8.4 respectively.  Our process for
creating the windows binaries for maplotlib requires a copy of the
Tcl/Tk headers.  The last time I tried to make a 2.2 version of
matplotlib,  I was able to get matplotlib to compile and link using
different Tcl/Tk headers (8.3), and matplotlib imported successfully, 
but it was unstable.  So,  my impression is that the problem boils down
to getting Python-2.2 specific support for Tcl/Tk into win32_static.
