answer to myself: I realize that collective.lead should work with SQLAlchemy
0.3, I guess that this is the reason for the error.

But I don't understand why it should work the rdbexample from the grokapps
repo, any special instructions?

I really want to work on this, but I don't understand all the parts yet. For

not big deal.

I'm not sure to understand Martin.

I thought that zope.sqlalchemy was born to unify all the developments on
sqlalchemy integration (collective.lead included). am I right?

I'm really newbie on Zope3 and Grok, so maybe I will understand your point
in some time
