Actually, there's a problem on Unix that may not exist on
Windows. Python is installed in <PREFIX>/lib/python<version>/. This
lets us have multiple versions of Python installed at the same time,
which is a good thing.
Now, installed packages and extensions go in
<PREFIX>/lib/python<version>/site-packages. This means that you can't
use *any* of the previously installed packages in the new
version, even if they were pure python. Since I use TMDA, my mail
stopped working when I installed python 2.4.
The real solution is a database of installed packages (which may well
be needed for the apt-get/CPAN functionality that people want) so that
a single python script can fetch and install all the installed
