Actually it *wants* to look in the right place, as shown by
ld --verbose | grep SEARCH_DIR

But it's probably being forced to look in the wrong place by a 
-L/usr/lib switch. Bug in the Makefile, perhaps in autotools as this 
crops up often (I don't use autotools so not sure).

Or let the linker do its work without interfering with its builtin 
search path. I think that would be the proper fix, rather than the 
workaround of not having anything in /usr/lib.
