-- Check the sort program referenced in the 'htmerge/Makefile' directory.  
   If it is '/bin/sort', change it to '/usr/local/bin/sort'.  This will
   insure that the superior GNU sort is used.

-- If you get this runtime error:

   .1: ./htmerge: fatal: libstdc++.so.2.10.0: open failed: No such file
   or directory
   Killed

   set 'LD_RUN_PATH' during compile time to the directory for
   libstdc++.so ... as follows:

   setenv LD_RUN_PATH /usr/lib:/usr/local/lib
