`private' takes symbol (identifier object, represented by Fixnum in
1.4.4), and makes visibility of instance method into private.  If you
want to change visibility of class method, you use either

  (a) use `private_class_method', e.g.

      private_class_method :one

  (b) use individual class difinition, e.g.

      class Foo
        class <<Foo
          def one
            ...
          end
          private :one
        end
      end  

Hope this helps
