[Zope-DB] ZpsycopgDA installation

[Leonardo Fernandes]

I did finish the installation. Just for someone else with the same problem I did have
to change permissions for the ZPsycopg files in Products directory and also to build
mxDateTime from source to install it on zope`s python (the RPM install it in /usr).

One final issue is this warning on starting Zope:

WARNING: Python C API version mismatch for module psycopg:
  This Python has API version 1010, module psycopg has version 1007.

Is it a serious problem?

Thanks everyone that helped
Leonardo.
