I allowed 2.0 to upgrade my 1.8.4 configuration, could that have been
the mistake? I'm not sure where IBCustomDataSet came from.

I don't know. This is a Xubuntu 18.04 box, I haven't used Delphi since
Delphi 7.

Maybe not, but my point is that I was running the 1.8.4 .DEBs from
SourceForge with no problems. I was a research chemist who had to
teach himself how to program, not a computer scientist, and errors
from deep inside code libraries tend to throw me, especially when it's
object oriented code (yes, I'm that old).

Anyway, I started uninstalling packages, and I do now have everything
building correctly. Now it's just a case of finding out what I need to
try to put back in again.
