Gnuplot Question:

Gnuplot is in widespread use on many platforms, including MS Windows, linux, unix, and OSX. The current source code retains supports for older systems as well, including VMS, Ultrix, OS/2, MS-DOS, Amiga, OS-9/68k, Atari ST, BeOS, and Macintosh. Versions since 4.0 have not been extensively tested on legacy platforms.

Please notify the FAQ-maintainer of any further ports you might be aware of.

You should be able to compile the gnuplot source more or less out of the box on any reasonable standard (ANSI/ISO C, POSIX) environment.
