[Zope] Uninstall a zope built from source

Hello, Some time ago, I built zope from the sources and it worked well. Now I prefer the way Debian easily offers instances and an init.d script. I would like to uninstall the Zope from the source bt I can't find a target for make to do an uninstall. I have a googled for a while without success. I have few folders named zope in the /usr/local, /var/lib and i am not always sure they belongs to the source install or the debian version. * Does anyone knows about a uninstall script? * If I have to do it by hand, where can I find docs that tells what to remove? (the install python script is long) How to be sure everything is gone? Have a good day,
