I've made a bit of progress.  On line 46 of the gnuplot.rb, I changed:
cmd += " -persist" if persist to :
cmd = "C:\\Gnuplot\\gnuplot.exe" + " -persist" if persist

The graph pops up for a very brief period and then terminates.  The 
program is the sine wave example from the ruby/gnuplot home page how to. 
It appears as if the pesist flag is not working correctly, but I'm not 
sure how to fix this.

-j
