I am trying to install psycopda for zope 3 by following the instructions in the readme file with the svn checkout of this product and I get the following error when starting Zope. I have tried searching for rdb module but have not found anything of use. I am using Zope 3 as installed by Ubuntu. Any ideas please? regards garry from zope.rdb import ( zope.configuration.xmlconfig.ZopeXMLConfigurationError: File "/var/lib/zope3/instance/sandbox/etc/site.zcml", line 7.2-7.55 ZopeXMLConfigurationError: File "/var/lib/zope3/instance/sandbox/etc/package-includes/psycopgda-configure.zcml", line 1.0-1.31 ZopeXMLConfigurationError: File "/var/lib/zope3/instance/sandbox/lib/python/psycopgda/configure.zcml", line 6.2 ImportError: No module named rdb
