Thanks, Jonathan. I hadn't realised this.

Yes, I had sort of imagined this.

This is what Bruno suspected, too, but I can't see what is pointing
to the old gwTeX binary directory here. Probably my ignorance.

I've done this, and it works, of course. Bruno asked why I thought
teTeX was being used. As he surmised, teTeX was in the path to the
various LaTeX input files read during typesetting and recorded in the
log. Now it is replaced by TeXLive.

Yes, I understand this, but the old directory path eludes me.
Many thanks to you both.
