I recently (June '99) compiled/ported Amaya V2.0a to Digital UNIX V4.0D. If you'd like a tar of the installation hierarchy (/usr/local/Amaya), get in touch with me.
The archive is relative to /usr/local/, and I recommend untarring back there. You may also want to make a link from /usr/local/bin/amaya (or whereever you put that kind of thing) to /usr/local/Amaya/applis/bin/amaya
