[Zope] compiling Python modules for Zope

Hello: I'm trying to get LoginManager to work, which means building DynPersist in ZPatterns. I followed the instructions of copying Makefile.pre.in into the ZPatters folder and running "make -f Makefile.pre.in boot". The main error I seem to be getting is: ../../ZODB/cPersistence.h:89: header file 'ExtensionClass.h' not found ExtensionClass.h is located in my Zope directory in lib/Components/ExtensionClass/src/ExtensionClass.h. How do I tell make where to find this file and any other headers it needs in order to build Python modules for Zope. Sorry, I don't know too much about make or compiling modules. Thanks! -- Mark James Adams mark at raysend dot com
