Hi,

Given the above, it sounds like the problem lies in either gnuplot or
gnuplot-mode.  It may be worthwhile testing out the gnuplot command
directly from a terminal (if it doesn't work there it won't work
anywhere else).

Since the problem seems to lie upstream from org-plot, please
ignore/undo the second instructions I sent in the previous email.

Sorry I can't be of more help.  Maybe the maintainer of gnuplot-mode[1]
could be of more help.
