I might be able to help. I am running Gnuplot 4.4.2 on Mac OSX 10.6.6, but not the MacPorts version. I had to get rid of the MacPorts Gnuplot and AquaTerm to compile Gnuplot 4.4.2 (in /usr/local/bin). My son, who works for Apple, sent me a 64-bit AquaTerm package, which I'd be happy pass on.
I don't have any problems with "pgncairo". I just produced "transparent.2.png" from the "transparent.2.gnu" script. In fact the pgncairo terminal produces a "test" png with
transparent filled polygons.
I compiled Gnuplot 4.4.2 following the instructions at <http://tinyurl.com/4qvc4el>, but AquaTerm wasn't available to Gnuplot until got rid of the MacPorts version of AquaTerm, installed the 64-bit version, and recompiled Gnuplot 4.4.2.
