Yes. But note that you have to be root to do that! (See also the
instructions in EasyInstall.txt, under the --site-dirs option, which
explains the same idea.)

And adding the directory to --site-dirs, which by default reflects only the
standard Python .pth-supporting directories.
By the way, with 0.6a6 (currently in CVS), there's another option. If you
put the setuptools egg directly on PYTHONPATH, it will process .pth files
in all PYTHONPATH directories. I added this specifically to make more
"traditional" non-root installs easier. You still have to add the
directories to --site-dirs, however.
0.6a6 also includes a vastly trimmed-down version of Ian's non-root install
script, with fewer options and bells and whistles. You simply give it a
'--prefix', which defaults to '~', and it doesn't munge siteconfig or
distutils.cfg or any of that.
Please give 0.6a6 a whirl and let me know how it works for you, as I'd like
to be sure these changes (including the dependency resolution algorithm
change) work well for TurboGears. Right now your package is the biggest
source of fresh test subjects uncontaminated by prior knowledge of how this
stuff is supposed to work. :) But the flip side is that I want to make
sure nothing I do results in a huge breakage that causes a backlash against
