[Zope] newbie installation problem Zope-2.2.5 on ppc linux

[Richard Weltman]

hello - can anyone offer some advice on this error message,
from a new installation of Zope-2.2.5 on YellowDog Linux 2.3
ppc ?

(stderr.txt pasted below)

the Zope server was compiled from source, by root,
and built in /usr/local/Zope-2.2.5

I'm new to Linux, but is it saying that the permissions on
this directory are set wrongly ?

contacting http://localhost:8080 shows that the server hasn't
started

and I got the same message when I tried the Mac OS X binaries
(in OS 10.1.5) to try and find out what was going wrong

TIA
cheers
Richard
