[Zope] Unusual 2.7 runzope fail message!

[Bob Bernstein]

Without apparent incident I have built Zope2.7 from the tarball,
using Python 2.3.3 (threaded) on this fairly current NetBSD
system. I create an instance under /usr/local and in etc/zope.conf
set an 'effective user', one that I've used for months now with my
Zope2.6 installation on this machine. Here's the output:

trollboy /usr/local/zope27 # bin/runzope &

    initgroups.initgroups(effective_user, gid)
AttributeError: 'module' object has no attribute 'initgroups'

nb: 

If I build and run Zope2.7 entirely under an ordinary user's
$HOME account on this NetBSD system, the thing launches and runs
with no complaints at all! 

And, I don't see the errant behaviour on an OpenBSD 3.5 system in
my possession, using a similarly hand-rolled-from-tarball Zope2.7.

Does this ring a bell with anyone??
