Hi: I'm new to zope and yesterday installed zope 2.8.4 on a linux system running python 2.3.5 Having followed installation instructions I got to the point of 'zopectl start' and got the following error message while trying both 'runzope' and 'zopectl'. I've tried installing different versions of Zope and get the same error (error absent with Zope 3). At one point, Zope did start (I moved it to a different port) but when I tried installing Plone in the Products directory of the zope instance, the 'Plone Site' did not show up in the drop down menu on the right hand side of the ZMI. Which is why I decided to reinstall and have been getting errors since. I haven't messed around with the Python installation at all. In this latest install I ran 'make instance' intead of 'make install' just to see if I would get the same error as I did yesterday when I had an instance of Zope running and I did. Any help in trying to fix this would be highly appreciated. I've tried changing PYTHONPATH in the zopectl file but that just leads to more and more errors.
