I don't normally include the man pages with the distribution because
they are so out-of-date. I can tar them up for you if you need them.
Just email me offline.

Just FYI: we don't have a man page for "ncl".

The compiler may need help finding the X11 libraries.  Look for a file
like:

     /usr/X11R6/lib/libX11.a

If you see it, then you need to include "-L/usr/X11R6/lib" on the
compile line (the path may be different; I'm just using
"/usr/X11F6/lib" as an example):

    ncargex cpex08 -n
    ncargf77 -L/usr/X11R6/lib -o cpex08.f cpexcc.f

If this works, *and* if you need to use ncargf77, then you can edit
$NCARG_ROOT/bin/ncargf77 and add -L/usr/X11R6/lib to the "libpath"
line:

set libpath = "-L/usr/X11R6/lib -L$libdir $syslibdir"
