As we have known for quite a while now, libltdl's error reporting is 
not sane.  For example, the preloader always issues a useless error 
("file not found") when preloading is not used for the module.  Since 
the loaders were nicely modularized, each loader is tried in turn 
(issuing an error on failure) until a loader is successful, or there 
are no more loaders.  This is perhaps worse on OS-X where there are 
two OS APIs for loading modules.  I think that some improvements were 
made, but functionality is still lacking.
