Can you bisect and determine which changeset caused the difference in 
behavior?

If it is something that happened recently, maybe it is an unintended 
side effect of this change:

  http://hg.savannah.gnu.org/hgweb/octave/rev/262cdfc6faf9

which made the load_path class use the absolute canonical directory name 
as the key for the private function map?
