Subject: module inheritance

I'm trying to modify a module but I can't seem to access it's private
functions.  This is for a rails app but I can't find the help I'm
looking for on the rails list and it's more of a ruby question than a
rails question.  I'll list my code and then the error.

module ActionController::Caching::Pages
  include ClassMethods
  # Expires the page that was cached with the +path+ as a key. Example:
expire_page "/lists/show"
  def expire_each_page(path)
    return unless perform_caching
    logger.error("EXPIRED ALL PAGES: #{path}")
    File.delete(page_cache_path(path)) if
File.exists?(page_cache_path(path))
    Dir.foreach(page_cache_path(path)) {|x| benchmark ("Got " + x) }
    rescue
  end

  private
    def page_cache_file(path)
      name = ((path.empty? || path == "/") ? "/index" :
URI.unescape(path))
      name << page_cache_extension unless (name.split('/').last ||
name).include? '.'
      return name
    end

    def page_cache_path(path)
      page_cache_directory + page_cache_file(path)
    end

end

The two private methods are copied directly out of the file I'm trying
to modify.  I don't want to copy these methods into my plugin.  If I
leave out the private methods, rails quits and complains about not being
able to find these methods.  I just want to inherit them.  Can you
inherit private methods?  The file I'm trying to inherit from can be
viewed at.

Thanks in advance for any help!
