just to eliminate scite as the cause of the problem cd into the directory
containing the files, start irb, then do

   system 'gsview32 mout.ps'

if that works then also try

   ruby -e"  system 'gsview32 mout.ps'  "

(assuming mout.ps exists of course)

my hunch is that it should work.  if it doesn't then i would guess that
'system cmd' is missing some env vars you have set elsewhere somehow.
