[Grok-dev] megrok.rdb setup error

Thu May 10 16:26:53 UTC 2012

Hi to all,
I'm new with Grok!

As in http://grok.zope.org/documentation/how-to/orm-using-megrok.rdb-and-sqlalchemy

I have added megrok.rdb to setup.py

install_requires=['setuptools',
          ...
          # Add extra requirements here
          'megrok.rdb'
          ],

than run bin/buildout

restarting Grok I see this error:

# bin/paster serve --reload parts/etc/deploy.ini

If I try with sqlalchemy it works!

Thanks a lot!
