PI emacs -- core dumps!

[Seth Teller]

i installed emacs on our new PI today-- this was the version i used:

Reading product descriptors from ...
        emacs   643922662   Emacs Option

i selected everything, installed everything, and checked that
everything had new dates.

but... invoking /usr/bin/emacs gives

Illegal instruction (core dumped)

i think my environment, etc., is correct:

ELIBDIR=/usr/lib/emacs
EPATH=/usr/lib/emacs/maclib

TERM=iris-ansi

etc.

what the @!#$%^& is going on?  can anybody shed some light?
