[Zope] NameError: CLIENT_HOME.

Hi, I'm trying to get ZEO 1.0 b3 and Zope 2.3.3 to play nicely together, but I'm struggling on some strange NameError. I followed the Advanced How-to of dshaw for setting it up; building from source made ZEO barf on the tests... looks like the tests are only for python 2.1? When I try zctl.py start, this is what I get: erik@somewhere:~/development/zope-farm/zope-2.3.3/instancehome$ ./zctl.py start Starting default Zope... Traceback (innermost last): File "/home/erik/development/zope-farm/zope-2.3.3/softwarehome/z2.py", line 547, in ? zdaemon.run(sys.argv, os.path.join(CLIENT_HOME, Zpid)) NameError: CLIENT_HOME Any ideas?
