[Zope] Problems importing Oedipus 0.07 into Zope 2.1.6 on Linux RH 6.1

All, Has anyone used Andrew Kuchling's Oedipus package (parses and displays ODP data from dmoz.org) with Zope ? In the Oedipus 0.0.7 distribution there is a .gz file with what looks like a Zope product distribution. But unpacking it in the usual place for zope products doesn't make it visible in my Zope Products folder. I am using Linux RH 6.1, Zope v 2.1.6, Oedipus v 0.07. Any known problems ? Do I need to have XMLDocument imported before Oedipus will import ? Help ! Nitin Borwankar, nitin@borwankar.com
