Hi; I built Z3 from FreeBSD ports. Went to create an instance and got this error: root@server167:ports/www/zope3 (115) /usr/local/www/Zope3/bin/mkzopeinstance -d /usr/local/www/Zope3/main Traceback (most recent call last): File "/usr/local/www/Zope3/bin/mkzopeinstance", line 47, in <module> from zope.app.server.mkzopeinstance import main File "/usr/local/www/Zope3/lib/python/zope/app/server/mkzopeinstance.py", line 32, in <module> from zope.app.authentication import password File "/usr/local/www/Zope3/lib/python/zope/app/authentication/__init__.py", line 19, in <module> import interfaces File "/usr/local/www/Zope3/lib/python/zope/app/authentication/interfaces.py", line 22, in <module> import zope.security.interfaces File "/usr/local/www/Zope3/lib/python/zope/security/__init__.py", line 24, in <module> from zope.security.management import checkPermission File "/usr/local/www/Zope3/lib/python/zope/security/management.py", line 25, in <module> from zope.security.interfaces import ISecurityManagement File "/usr/local/www/Zope3/lib/python/zope/security/interfaces.py", line 20, in <module> from zope.interface.common.interfaces import IAttributeError File "/usr/local/www/Zope3/lib/python/zope/interface/common/interfaces.py", line 80, in <module> classImplements(OverflowWarning, IOverflowWarning) NameError: name 'OverflowWarning' is not defined Now, apparently there is a vulnerability with Z3, so I could only make with this thrown in: DISABLE_VULNERABILITIES=yes TIA, Nancy
