I'm trying to build Zope 2.2 from the sources in a RedHat Linux 6.1 box (which has Gnome-Helixcode intalled as a GUI). The following happens after "python w_pcgi.py" executed as root, nevertheless other things do build, compile and install ok. Obviously Zope is not finding some include files. What would be the best approach to solve this: Thanks in advance, all help and suggestions are appreciated. Ed P.D: I know I could use the pre-compiled Zope distribution. I prefer and need to use sources.
