From your "ruby-head" log:

  $ ruby --version
  ruby 2.0.0dev (2012-12-12) [x86_64-linux]

It's too old.

Is there a technical reason to not allow re-binding a method from one module to any other module ?
 
  module M
    def foo; "foo"; end
  end

  module N; end
  N.send(:define_method, :foo, M.instance_method(:foo)) #=> should not raise
 
It's like monkey-patching. Powerful, dangerous, but also really useful. It could allow different variations of method_wrap or alias_method_chain that are not possible right now.
