Do you mean the above substitution will make something like
plot(y), where y=[2 4 6 8]
work from octave with carbon gnuplot from 
 http://www.tucows.com/get/203840_81894 ?

I tried this with no luck. I tried changing the name of pgnuplot, as
described above, with the same behavior.  I then changed the name of 
gnuplot-3.7.1d.app/Contents/MacOS/gnuplot-3.7.1d
to 
gnuplot-3.7.1d.app/Contents/MacOS/gnuplot
 and added it to path. That brought up two gnupolt terminals, but no
 plot.
