I have an up-to-date ~amd64 GenToo installation with has been
built on a current AMD64 (Phenom II) machine where I used
-mtune=3Dnative in etc/make.conf since I didn't think of the case
that I would need to port this system to a somewhat older Opteron
based machine (still AMD64)

But after cloning the system, some fundamental utilities die of
an illegal instruction.

Did you have -march set? = If so, what to?

If -march is unset, then AFAIK your binaries should = run on any amd64 machine. If you have it set to native, then your binaries = will only run on equal or greater hardware than what it was built on.
