At a Windows command prompt, the following Ruby script executes just
fine:

class Array
 def new_method()
   "Hello"
 end
end
puts [""].new_method

However, browsing to this script on my localhost (apache2) gives a
NoMethodError:

undefined method `new_method' for [""]:Array

I've tried with both mod_ruby and fastcgi bindings, but I can't get it
to work.  Is there a config. setting I'm missing?
