I'm not sure if I didn't ask my question correctly, because I've found a 
different answer to my question.  Maybe it's so obvious?  Anyway, all I 
had to do is create an environment variable LIBRARY_PATH and place 
/usr/X11R6/lib in it.

Here it is in my .profile member:
LIBRARY_PATH=/opt/local/lib:/opt/local/lib/db46:/usr/X11R6/lib
ex****t LIBRARY_PATH

(The other two libraries are to pick up libs installed using Mac****ts.)

Anyway, that does everything I require.  Or seems to at least!  :-)
