in C you can use both setenv and putenv, in csh it's setenv so I mix 
those things up :P

As of Apple's X11 - look in Applications -> Utilities and there should 
be X11. But XDarwin and other X11 are usually mutually exclusive, so I 
doubt that you have Apple's X11. I have no idea why someone would 
install XDarwin instead of Apple's X11 nowadays, it makes no sense to 
me, but maybe someone can explain that.

The "file" is just "gs" - GhostScript is just the name of the program 
is called.
