I guess qoutes surround command path are necessary.

    gp = GnuplotProcess.new('"c:\program files\design\gnuplot\gp371w32\pgnuplot.exe"')

Or, this seems better, put quotes in command for win32_popen4.

   def _win32_open_process(*cmd)
     require 'win32_popen'

+    cmd.collect! {|s| /\s/ =~ s ? %{"#{s}"} : s}
     IO.win32_popen4(cmd.join(' '))
   end
