I am trying to follow this (Apache-DSO-Fastcgi-Zope-ZEO installation) howto but using python 2.2 instead of python 2.1.2. The wo_pcgi.py throws an exception as follows: Compiling extensions in lib/python cp /usr/local/lib/python2.2/config/Makefile.pre.in . cp: cannot stat `/usr/local/lib/python2.2/config/Makefile.pre.in': No such file or directory Traceback (most recent call last): File "wo_pcgi.py", line 45, in ?
