I did it when I pasted the code in my previous answer:

require 'find'

module Froop
       def match(*paths)
               matched=[]

              # I changed this line adding "Find." in front:
               Find.find(*paths) { |path| matched << path if yield path }

               return matched
       end
       module_function :match
end

Froop.match("./") { |p| ext = p[-4...p.size]; ext && ext.downcase == "mp3" }

Jesus.
