I downloaded Zope and followed the INSTALL.txt directions. The installation stops at the following: rm -f *.so *.sl so_locations VERSION=`/usr/bin/python -c "import sys; print sys.version[:3]"`; \ installdir=`/usr/bin/python -c "import sys; print sys.prefix"`; \ exec_installdir=`/usr/bin/python -c "import sys; print sys.exec_prefix"`; \ make -f ./Makefile.pre.in VPATH=. srcdir=. \ VERSION=$VERSION \ installdir=$installdir \ exec_installdir=$exec_installdir \ Makefile make[1]: Entering directory `/usr/local/src/Zope-1.9b1-src/lib/python' make[1]: *** No rule to make target `/usr/lib/python1.5/config/Makefile', needed by `sedscript'.
