Jens, Thanks for the pointer to your Zope on MacOSX page. I built, tested and installed 2.1.3 okay and built (but haven't yet tested) Zope 2.6.0b1. Looking ahead in your instructions a bit, you mentioned a problem with sockets if the hostname doesn't resolve. I encountered this problem with other software on the system and got some help from one of the Mac-related newsgroups. In my situation, I have a cable modem connection to the net with an Xrouter connected to in and an airport sitting behind it. Each bit in the chain is doing DHCP. By default, OSX comes up with a wacky hostname, something like "SkipMontanarosComputer.local". The cure was to register with dyndns.org, download and run the appropriate updater program and edit /etc/hostconfig so the HOSTNAME variable is set to the desired value, e.g.: HOSTNAME=montanaro.dyndns.org This might be a useful addition to your instructions.
