[Zope] problem installing Openflow product of zope on LINUX

Hi, I am supposed to set up development environment for a project. & for that I have already installed Zope-2.11.4, Python-2.4.4, Egenix-2.0.6, Postgresql-7.4.13, & Psycopg-1.1.6 on a RedHat LINUX box. Now I need to install OpenFlow-1.1.0 in the Products directory of Zope. I tried installing OpenFlow source tar ball by the following instructions – ./configure Make Sudo make install All of the above commands worked successfully. But still I am not able to see the openflow product on the Zope Management Interface Screen. Can you please suggest something? It’s really urgent. Am I missing any steps while installing OpenFlow? Please Help me. Regards, Smita
