I encountered this same issue just a week ago and thought that the 
poor error was OS-specific and didn't realize that it was a libltdl 
bug.  If the missing symbol error had been reported, then I would have 
been a lot less confused.

Yes, I remember the former correct behavior.

When reporting errors, it is almost always most correct to report the 
first error encountered.
