Oops.  I was looking in the wrong directory.  There is some problem in
examples/tk/Makefile.am which I will look at.

Note this serious problem still exists (nothing from the bindings/tk _source_
tree is indexed), and I will work on it. I didn't see the results of this
problem before because I didn't try running the installed interactive tk
examples.
