[Zope] Zope SybaseDA not being loaded

After compiling from source and following all instructions by the readme file my zope server is not able to load SybaseDA as a product. This is the message which appears instead: File "/usr/src/packages/BUILD/Zope-2.3.1-src/lib/python/OFS/Application.py".... File "/usr/share/zope/lib/python/Products/SybaseDAv2/__init__.py", line90, in ? import DA File "/usr/share/zope/lib/python/Products/SybaseDAv2/DA.py", line 91, in ? from db import DB SyntaxError: duplicate argument in function definition (db.py, line 158) How can I fix it? I am running this configuration: SuSE Linux 7.2 Kernel 2.2.x Python 2.0 Sybase ASE 11.9.2 SybaseDA 2.0b2 Zope 2.3.1 (with ZServer) yours Sebastian
