I assume the original Emacs was installed via rpm. It would have the
versions of curses, terminfo etc that it requires specified as
dependencies. You'd have to do something quite special to break that,
and if you did, I imagine you'd get an Emacs that would simply not start
(due to missing libraries), as well as a system that was pretty much
broken altogether (because a huge number of packages depend on ncurses).
