[Zope] 2.6.0a1

Hi, just a tiny question, I'm trying to run Zope 2.6.0a1 on a Debian, but I always get the following error: ./start: "A user was not specified to setuid to; fix this to start as root" Then when I do the following, ./start -u root; I get: "/var/local/Zope-2.6.0a1/var does not have the sticky bit set; fix this to start as root." At the moment I'm out of possible ideas, I tried several things including changing permissions etc, but I always end up with above errors. Thanks in advance, Tom.
