That part is already solved by [3422].  The topic was about how to  
solve it better in the future.

This is setuptools issue #53 (respect the PYTHONPATH).  I submitted a  
patch to fix it and posted about it to the distutils-sig list:

http://mail.python.org/pipermail/distutils-sig/2008-November/ 
010487.html # patch: solving the two major things that people dislike  
about setuptools, part 1

PJE, the maintainer of setuptools rejected my patch, and some other  
people on the distutils-sig list replied to say that this was the  
last straw and they were going to fork setuptools.

Hopefully after Tahoe-1.3 release we can start using the fork and it  
will respect the PYTHONPATH.  Also, there's a possibility that we  
could contribute a patch to setuptools that PJE would accept that  
would also make it respect the PYTHONPATH, but I'm not precisely sure  
how it would work.  I intend to think about that at some point, but  
I've been awfully busy with Tahoe.  Please read the thread rooted at  
that URL above for full context.  See also, if you are curious the  
[[issue tickets]] tiddler on my klog which contains a (dizzyingly  
large) list of issue tickets that I'm trying to pay attention to.

That's a neat idea.
