I saw that in your note, and I really did notice that from the messages
that I sort of skimmed and couldn't dig into.  Thanks Edd and Thomas!

ncurses is there and that wasn't it; I added "set -x" to trace things.

I did get the summary that it wasn't built.  The reason (sorry for not
being clear about it) was:

http://git.savannah.gnu.org/cgit/libcdio.git/tree/configure.ac#n511

which was silent (without "set -x").

I would not have noticed if packaging fresh, but it was built under
2.0.0.  It may well have been nonfunctional though.

That indeed does not sound too useful :-)
