Nope, that still dosen't work.  I get the same 'all points undefined'
error.  Doug DeJulio says:

"I'm not sure, but I've been having a dialog with one of the gnuplot
support people about it.  It works if compiled under NS 1.0a, it works
if compiled under SunOS3.5 and you use atom(1) to make it a Mach-O
file.  When compiled under NS 2.0, bizarre errors occur.  The most
obvious error I've found is that anytime you input a constant, it's an
"undefined value"."

He sent me a file that was compiled on a Sun and then converted with atom.
It works fine.  It is a patch-level 1.0 version (with no FPU suport).

This will get me along for now but It would be nice to see this problem
solved.   

Thanks Doug!
