You're problem is right here: you speak of "the" Linux version, but such 
a thing doesn't exist.  There exist versions of gnuplot compiled by 
various people, including Linux distributors.  Some of them made rather 
sub-optimal configuration choices for their builds.

Because your Linux binary was built with the wrong PNG driver.  You'll 
see the difference if you "show version long" on both platforms and 
check the "Compile options" part.

gnuplot tries to keep scripts as platform-independent as possible, but 
the availability of terminal drivers and the options they support is 
where this ceases to work.  "set terminal" commands essentially cannot 
be fully portable.
