Ok, but if TclMagick is in the extensions/ module... that is going to
be difficult.

That makes sense.  Maybe --with-gm and --with-im, but what I was
really after is the way to just get it working at all, rather than
worrying about the two systems.

To do that I need, I suppose, a configure option that points to the
GraphicsMagic-config script.  Is that what the above does with the
$withval variable?

Would a separate, mutually exclusive --with-imagemagick be a bit
clearer?

Sure, that's what I'm interested in for now...
