I noticed that distutils installs itself under 'lib\site-packages'
which does not seem to be a convention under NT, at least the
directory does not exist by default, and is not in the Python path
by default.
It directory is added by site.py, which is imported when you
start python (unless you use 
"python -S").  Quoting from it:

Exactly. On Windows, the site directory is just sys.exec_prefix, rather
than sys.exex_prefix/lib/python<version>/site-packages.

So now we need additional fixes to distutils to handle this platform
difference.

Anyway, lib's "site-packages" is the official place for installing
Python packages.
On Unix ;-)

from your patch:
...
g['LIBDEST']=os.path.join(sys.exec_prefix, "Lib")
    g['BINLIBDEST']=os.path.join(sys.exec_prefix, "Lib")
Is that really "Lib" or just "lib"?  Granted, it is NT which means
I know nearly diddly about it.
I guess it should be 'lib'. I don't know. I just used 'Lib' cause that's
what the some other Python path directories (set in the registry) call it...

OK, here's two patches, one to handle the site-package platform
differences, another repeat of my last one, only this time with 'lib', not
'Lib'

With these patches distutils installs itself correctly on NT for me.
