All of a sudden at starting a Zope instance, I get this error message on
the console:
  File "/usr/local/zope/z2.py", line 476, in ?
    zdaemon.run(sys.argv, os.path.join(CLIENT_HOME, Zpid))
NameError: name 'CLIENT_HOME' is not defined
It worked before. I installed some CMF Content types and stuff, but
can't remember changing anything above of the Products directory.
