[Zope] MacOSX

I noticed in the how-tos that someone had managed to make a build of zope for MacOSX . Given that I know nothing about unix commands, is there a pre-made binary I can just drop onto my G4 (running OSX DP4) and run? Is this even possible or is it not the unix way? IS there a reason for there not being a macintosh version of zope, does the platform not allow it or is it just that nobody has wanted to do it tom
