The source code for this program is part of a package called ethertools,
written by Phil Budne (then of Boston University).  I don't know where it
might be archived, but I could send you a modified version, using a
library routine with this functionality in my ethernet access library,
available via ftp from cs.columbia.edu, in ~ftp/pub/etherlib.tar.Z, or in
the nearest comp.sources.unix archives.

Personally, I just use the following shell script, although it's not as
complete as my library routine, which will also use the
ethers.by{name,addr} YP/NIS maps (and even RARP!) in an attempt hostnames
and IP addresses to ethernet addresses.

#!/bin/sh -
set -e
/usr/etc/ping -r ${1?"Usage: $0 hostname"} 5 > /dev/null
/usr/etc/arp -a | grep $1
