Python needs a .../python2.x.y/vendor-packages directory
for vendor supplied Python files.

See:

http://mail.python.org/pipermail/python-list/2005-September/300029.html

for the full reasoning behind this request.

I also approached Guido w.r.t. this. Here's his reply.

I think that's a reasonable request. (In the mean time,
I think that
using site-packages is fine as an interim solution.)

I suggest that you use the SourceForge patch manager
for the Python
project to upload your patch, and then post to
python-dev. You may be
asked to review 5 other patches in order to have
someone look at your
favorite patch.
