[Zope] PCGI Error: (102) failure during connect to ZServer

This is with Zope-2.2.0b3-src.tgz The pcgi wrapper reports ...is unable to connect to the ZServer background process via Unix socket .../var/pcgi.soc I am trying to install this on a remote host, this error came up locally too, though. I followed glndspud's howto on 3rdparty host setup. With a 2.1.6 release I was able to get zope running. However, with this setup I was not able to login through manage, the authorization did not work. So my reasoning, an upgrade should make this error vanish. Not so, until now. ;-( Christian
