Thank you for both explanation and the pointer. I didn't even realize
until now that gnuplot port was explicitly overriding Macports'
default behaviour. I only concentrated on the gnuplot compilation and
makefiles.

I will do some more testing after removing that line, but there are
also a few other changes needed before closing your ticke anyway (I'll
write more about it into the ticket).
