Thanks (as always) Dima. There do seem to be more than one place where installation instructions can be found. I thought I was being a good citizen by actually reading the version I found instead of relying on my past experience.
Most of the build worked fine (but see below) after ./bootstrap && ./configure (after which "make configure" reports that 'configure' is up to date). I found that on a system running ubuntu 22.04.5 LTS the package qhull fails to build as it want cmake version 3.25 or higher while this system only has 3.22.1 available. I wonder if the later version is really necessary. I am hesitant to upgrade the OS as I do not have physical access to the machine without a lot of hassle: it is in a central university server room, and we don't like to remind the relevant authorities that they still house some of our servers. It is also 13 years old but still rather useful even if it still only has sage version 10.6 on it.
