Others have reported success with the binary-format disklabel.
The ECOFF version may be newer than your kernel supports, or the
Ultrix disklabel ioctls may have changed.   From here it's hard
to tell.

The ultrix-binary disklabel program that writes a NetBSD disklable is
something that Ted Lemon created. The only Ultrix systems I have
access to are running 4.2a; they will also produce a version 2.10
ECOFF binary.

.then i treid to recompile it from the sources in disklabel.tar.gz but this

I verified that "bmake CC=gcc" (bmake is Berkeley make) recompiles
disklabel, from the source in the tarfile, on an Ultrix 4.2a system.
The resulting binary is on ftp.netbsd.org, with the source, as
 'ultrix4.2a-disklabel'.    I'm not sure how much more I can help,
remotely, without access to an Ultrix 4.3 system.

You might like to check the port-pmax e-mail archive, there may
be more on this there.
