Maybe 
Well it works in an ruby prog.  It maybe it truly is MRI issue.

Seee if I can fire up j/iron ruby

args.rb below:
==================
require "rbconfig"


puts "The name of the progrma laucnhed is #{$0} OR #{$PROGRAM_NAME}"
ARGV.each do|a|

  puts "Argument: #{a}"
end

puts "And finally the ruby executable #{ENV['_']}"


puts File.join(Config::CONFIG["bindir"],Config::CONFIG["ruby_install_name"])
================
