If you don't need to support deep class hierarchies you don't need
class variables, so I'd use the simpler class instance variables
instead. I'm not sure why you decided to split the functionality into
a module and a base class, but if you want this structure, here's how
I would code it (but I don't claim to know the "right way"...)

  module MethodCollector
    def self.included( klass)
      klass.extend ClassMethods
    end
    module ClassMethods
      def addpoint(name)
        extra_methods << name
      end

      def add_method(name)
        define_method name.to_s do
          "MethodName is: #{name}"
        end
        addpoint(name)
      end
    end
  end

  class MethodAdderBase
    include MethodCollector

    def self.extra_methods
      @extra_methods ||= []
    end

    def extra_methods
      self.class.extra_methods
    end
  end
