I'm pretty sure this is written somewhere, that you should put just
the 'zope' and 'persistent' packages on PYTHONPATH. I usually make
symlinks from the z3 installation to a 'five' directory and put that
in the PYTHONPATH instead.

The only "intuitive" interface is the nipple.  After that, it's all learned.
