Usually you do

require 'facets/foo'

and have a file "xyz.rb" in facets that will link "more/foo.rb" or 
"core/foo.rb" depending on where it's located.

You could as well do this: create a file "facets.rb" in the same 
directory that holds "facets" (i.e. lib).  Inside of that you do

def frequire(*names)
   names.each do |name|
     %w{more core}.any? do |base|
       begin
         require "facets/#{base}/#{name}"
         true
       rescue
         false
       end
     end or raise LoadError, "Did not find #{name}"
   end
end

Or something similar.
