[ZODB-Dev] unable to import ZODB: class ConflictError, AttributeError

[Ralf Hauenschild]

Hello guys,

i've been desperately trying to install ZODB3 via the following ways:
- easy_install ZODB3
- installation of Zope2
- manual installation of ZODB3, preceeded by installation of the 
requested packages from pypi

I'm using Ubuntu and Python 2.6.

Whe trying to import ZODB, I'm still getting the following error:
