It didn't seem to be resolved anywhere else; I had to do

	nm -o /usr/local/lib/lib*.a /usr/X11/lib/lib*.a | grep ...

in order to find the lib in the first place, and it doesn't appear
to be resolved anywhere in the local .o files.

I'll go check again, but I'm still very puzzled.

Noted; but since I'm not on it, could you please cc: me?  [I'll
be rectifying this shortly...]
