We don't need another setup variable for this. Just place a
well-known module into the site-packages/ directory and then
query it's __file__ attribute, e.g.
site-packages/site_packages.py
The module could even include a few helpers to query various
settings which apply to the site packages directory, e.g.
site_packages.get_dir()
site_packages.list_packages()
site_packages.list_modules()
etc.

Just in case you don't know...
python setup.py install --home=~
will install to ~/lib/python
The problem is not getting the packages installed in a non-admin
location. It's about Python looking in a non-admin location per
default (as well as in the site-packages location).
