The on-going changes to make seem to have broken badly!  The following 
is running on an amd64 dual-core system...

===> build.sh command: ./build.sh -T /usr/obj/tooldir/x86_64/amd64 -D /usr/obj/destdir/amd64 -O /usr/obj/objdir/amd64 -R /usr/obj/reldir -m amd64 -j4 -x -u release iso-image
===> build.sh started: Fri Oct 12 17:37:17 PDT 2007
===> NetBSD version:   4.99.33
===> MACHINE:          amd64
===> MACHINE_ARCH:     x86_64
===> Build platform:   NetBSD 4.99.31 amd64
===> HOST_SH:          /bin/sh
