Die Ursache war, dass etwas anderes als die in virtualenv installierte Pyramide verwendet wurde.

% which pserve
/usr/local/bin/pserve

Nachdem ich die auf meinem System installierte Pyramide deinstalliert und die virtuelle verwendet hatte, trat der obige Fehler nicht mehr auf. Siehe auch

% which pserve
