Initially I hadn't told Hi-Toro where E-UAE was located. I've now done that, but it still won't run because I don't have the SDL framework installed. I've just downloaded that and have realized the developers have made no effort whatsoever to explain to UNIX newbies how to install it. They seem to assume that everyone wanting to install it is a UNIX guru and intends to code their own apps.
Anyway I found this 'Fink' thing which supposedly makes the installation child's play. We'll soon see. Actually 'soon' is the wrong word. I've got to download a 17mb file with a dialup connection. Oh well, I'll begin thumb twiddling.
