If you reverse the order you should get a better result:

  >> gnuplot_binary /tmp/junk
  >> graphics_toolkit gnuplot
  error: __init_gnuplot__: the gnuplot program is not available, see 
'gnuplot_binary'
  error: called from
      graphics_toolkit at line 85 column 5

I think patches would be welcome to fix this with the order you have,
but it's not clear to me how the gnuplot pipe is managed, under what
conditions it is opened and closed. It seems safest not to change what
gnuplot_binary points to after the toolkit has been activated.
