Uh-oh.  I do not know what I was looking at when I wrote that.  The
link just failed the same way.  And that was after `make clean`. 
OTOH, I see that you added those lines earlier in the file than I did

Meanwhile I accomplished the link by typing the command at the command
line, including -lrt.

I am sorry for having given you false encouragement.
Terry.
