Thanks for looking at it. I don't particularly need it, I just wanted
to report the build failure.

Actually, I built it with xtrans enabled and tried running an xterm
against it, but gave up after about 4-5 minutes where nothing
happened. (xterms without xscope start immediately.) Perhaps I was too
impatient.
