[Zope] configure '--prefix' or '--home'

It appears that when Zope 2.7.0 is getting built, any value for --prefix is being copied to --home and the latter variable used, and wondered why... Within the Makefile, is there any particular reason why '--home' is being used here:- ? install: build ${PYTHON} "${BASE_DIR}/setup.py" ${DISTUTILS_OPTS} install \ --home="${PREFIX}" ${BUILD_FLAGS} ${INSTALL_FLAGS} If this was '--prefix', as one might logically expect, it would build without any problems on OS/2. I notice that the Windows version includes '--prefix' at this point. I would like this to be changed to '--prefix' if the command line includes this option. Is that possible? -- John
