Hmm, maybe I wasn't clear enough: I think that a distutils
package should have a flag in its setup.py which lets distutils
tell whether it's a site package or a system package, e.g.
setup(... pkgtype='site-package' ...)
vs.
setup(... pkgtype='system-package' ...)
(with pkgtype='site-package' as default value if not given)
The user would in both cases type 'python setup.py install'
but the install command would automatically choose the
right target subdir (site-packages/ or system-packages/).
