Subject: Broken alias behavior in Ruby 1.9.2?

The following code works in Ruby 1.8.7 but not in 1.9.2, instead, I get
the error:
NoMethodError: undefined method `old_encode64' for Base64:Module

Can someone please shed some light on this.

Thanks in advance,
Tron

module Base64
  alias :old_encode64 :encode64
  module_function # this seems to be necessary -- get a "wrong number of
arguments (2 for 1)" without it this line.

  def encode64(bin,options={})
    if (options[:no_line_break] == true)
      old_encode64(bin).gsub(/\n/, '')
    else
      old_encode64(bin)
    end
  end
end
