Take thiw with a grain of salt as my knowledge of such things is very
rusty, but there used to be several ways:

  0) use "-L/usr/X11R6/lib64" on the command line; my concern is that
     the compile might still pick up the other area first.

  1) set the LD_RUN_PATH variable or the -R switch appropriately; this
     "burns in" the library search path to the executable.

You can of course also override this at runtime (after INSTEP4 in other
words) with LD_LIBRARY_PATH but that's a hack.

Eric and the others can probably advise how best to use these in the
context of AIPS.  Probably in the FDEFAULT.SH and CCOPTS/LDOPTS files.
