You are not the first one having problems with Zope + Apache installation.
If you manage (I am sure you will) to install Zope+PCGI+Apache, please write us what was the cause of your problem.
Main cause was not having your excellent howto at hand. Is it referenced at www.zope.org? I did not run the installation from the start, because I do not use precompiled binaries. I just run thru it and found this: 1. although I chowned Zope installation tree to nobody, I always started zope as root 2. Zope.cgi was owned by root instead of nobody. 3. I was always starting Zope with "python z2.py" instead of "./start"
It would be very nice to collect a list of troubles with Apache+Zope installation.
Sure, here it is and thanks a lot for your help. -- Milos Prudek
