[Zope] Still More Problems On the Install...

Hi; Okay, I've untarred the distro. The instructions said to type in *python w_pcgi.py*. Did so and lots of stuff printed to screen, the last of which was *SystemError 512*. Should I worry about that? Then I thought I was supposed to type in *./start* but it didn't recognize that command. I'm running Python 2.2.2. Thanks for your help. BenO
