Hi Paul,

Thanks for the swift response.

You're right.  I guess my working directory had gotten out of synch with
something.  After a `git reset --hard master && git clean -d -x -f', and
applying the patch again freshly, it works perfectly well, and without
the problems of undefined symbols like the previous patch.

Sorry for the noise.

I'll reply in that thread when I've had time to try it.
