[I'm a bit unsure where this belongs. It's obviously not -current.]

I am trying to build a 1.5.4 snapshot on a 1.6K mac68k box. By
chrooting to a 1.5.4alpha snapshot this goes pretty well, but then
stops in '/usr/src/distrib/mac68k/instkernel/ramdisk' with

cc -static -o ramdiskbin ramdiskbin.o cat.cro chmod.cro chown.cro chroot.cro cp.cro dd.cro df.cro disklabel.cro ed.cro fsck.cro fsck_ffs.cro ftp.cro gzip.cro ifconfig.cro init.cro less.cro ln.cro ls.cro mkdir.cro mknod.cro mount.cro mount_cd9660.cro mount_ffs.cro mount_msdos.cro mount_nfs.cro mount_kernfs.cro mt.cro mv.cro newfs.cro ping.cro pwd.cro reboot.cro restore.cro rm.cro route.cro sed.cro sh.cro shutdown.cro slattach.cro stty.cro swapctl.cro sync.cro test.cro tip.cro umount.cro sysinst.cro pax.cro tset.cro -L/build/destdir/usr/lib  -lbz2 -ledit -lutil -lcurses -ltermcap -lrmt -lcrypt -ll -lm

-- when I try the command sequence 'outside' the chroot, i.e. with the
1.6K binaries, the result is the same:

-- Any ideas? How do others build 1.5.x snapshots?
