Hey all, I hit a snag with the xml-object gem on MacRuby; the code works on MRI 1.9.2. A simple test case:

$ macgem install xml-object
$ macirb
> 
require "rubygems"
require "open-uri"
require "xml-object"
o=XMLObject.new(open("http://www.w3schools.com/xml/simple.xml"))

NoMethodError: super: no superclass method `initialize' for #<XMLObject::Adapters::REXML::Element:0x2004fbea0 ...>

The same test case works fine on MRI 1.9.2.

Let me know if there's a better place to report issues like this.
