[Zope] Zope Components and ZPatterns

In trying to install ZPatterns on linux the install fails during the "make" part of the install, complaining about a non-existant ExtensionClass.h, which should be in the Zope Components directory (also not existent). I noticed on the mailing list that one should do a rebuild if you install from the source. I ran the install script that comes with the source but still no Components directory is created and no ExtensionClass.h is to be found. Where do I go wrong? Waiting for ZPattern-magic Roché
