There is little fear, uncertainty or doubt about this. The problem is
that this represents a huge change of behavior for users making the
transition to Leopard. On Tiger, a user could download any basically
any python pacakge and do "python setup.py install" and things would
work. Now under Leopard, this becomes "python setup.py install" +
muck with PYTHONPATH or .pth files. I personally have no problem
doing this, but many of the casual python users with whom I work will
be tripped up by this....and they will come and ask me what to
do....over and over again....
