"Pd-extended is broken" is much too broad.  Saying the whole thing is  
broken doesn't help anyone.  The problem is somewhere in the  
relationship of the libdir loader and Pd's logic for checking if it  
has already loaded a binary library.  If you load a libdir called  
"blah", you won't be able to load [blah/blah] or [blah].
