That's true, but why do we bother about Emacs being installed from an
rpm?  That's _really_ the job of whoever prepares the rpm.  They have
the same problem with GDB, for example, which installs libbfd.

I thought we are talking about "make install", where we do control
things.  Does it make sense to refrain from overwriting at that time?
