... you should never tests things like a new version of your backup
software on a production server anyway.

In general it is safer to deinstall an old version of a package before
building the one. Only few software packages have a build process which
makes 100% sure that only sources, includes and libraries from the build
tree are used. "lesstif" and the "gnome" family are examples where a
succesful update doesn't work with an old version installed.
