I think we need to see your command-line arguments and whether you're
putting them before the name of the Ruby script or after.  Are you
invoking the script like:

    ruby script.rb arg1 arg2

or:

    ruby arg1 arg2 script.rb

because the first is what you should be doing.  Alternatively, do you
have RUBYOPT set or do you invoke any arguments on your #! line (if
you're on a Unix-like system).
