Also, this wouldn't work as intended on a system where more than one
arch of the emacs package is installed - eg. on my system i seem to
have emacs.x86_64 and emacs.i386 installed, and so

rpm -q --qf=%{VERSION} emacs

 gives 22.0.9922.0.99.

Granted, that wouldn't happen in a mock chroot buildroot, but still, I
think we should do a bit better than that :) Can't see how though :(
