I update a port Zope-2.5.0_1 to fix security problem. See: http://www.zope.org/Products/Zope/Hotfix_2002-03-01/README.txt And I remove two files pkg-install and pkg-deinstall. These files which create www user and group are not needed in 4-stable.
Responsible Changed From-To: freebsd-ports->nbm Over to maintainer
State Changed From-To: open->closed Hotfix patch applied - am leaving www user until I see other ports not worrying about it
