  a patch designed to fix the sort of problem that I reported.

I'm now in the same position vis-a-vis the various computers as 
when I first reported the issue.  I'm afraid things get weirder.

(1) Before applying Daniel's patch, the situation is as I 
described yesterday.  But, taking Ethan's idea, I also tried

   echo "show version long" | gnuplot

and this worked OK.

(2) After applying Daniel's patch and recompiling, my "set term 
png" echoed to gnuplot produced a failure (as before), but in 
addition

   echo "show version long" | gnuplot

now produced the same X11 failure!

waverley:~$ echo "show version long" | gnuplot

gnuplot: unable to open display ''
gnuplot: X11 aborted.

I then reverted the patch, recompiled, and tried again.  At least 
the results seem stable: "show version long" piped to gnuplot 
worked, "set term png" failed.
