I can certainly appreciate that problem.  Zope gets to cheat on that by
leveraging Python for most of the painful bits.

Heh, if that serves your bliss, sure. :)  I really just meant to
indicate that modern Pythons can always do a better job of telling where
their 'site-packages' is than heuristics / guessing.  I know you still
support some pre-distutils versions;  for those, happy-chance is the
best you can do.
