You wouldn't have to rely on test scripts and experimentation so much if 
you read more of the documentation first ... 'show version long' would 
have told you the story right away.  Your two gnuplot executables use 
two different PNG drivers, written independently of each other, using 
different support libraries.  One directly talks to libpng, the other 
goes through libgd.  The latter is by far the more powerful.

It didn't have libgd (development) packages installed when gnuplot was 
built there.
