[Zope] Setuid

Blank to all I have installed zope-2.6.0_1 on freebsd 4,7 stable but I have of the problems to make to start it. If launch zope from root with su-2.05b# ./start I receive this error SystemExit: A user was not specified to setuid to; fix this to start as root (see doc/SETUID.txt) I have tried also always launch it with l option - u from root su-2.05b# ./start -u slupz SystemExit: /usr/local/www/Zope/var is not owned by root, fix this to start as root (see doc/SETUID.txt) Someone puo gives to me one aid hand? Thanks to all. Excused for my English.
