This isn't what you want.  What you want to do is point PYTHONPATH to a
staging directory of some sort, and put that directory on the "develop"
line.  What you're doing here is trying to install the library *onto
itself*.  -d and PYTHONPATH need to be some *other* location, to which
you're installing.

mkdir ~/py_lib
export PYTHONPATH=~/py_lib
cd ~/sa020
python setup.py develop -d ~/py_lib
"""

i.e. you need to put the egg on PYTHONPATH in order to override the
system wide installation, *not* the directory which contains the
source code.
