When running ldconfig, it saves the information in the 
/var/run/ld-elf.so.hints file, and I assume that ld should then know
where libraries are located, since they are in this cache file.  So when
running: ld -lexpat, why did ld not know the location of the expat
library, when it is in the cache (hints) file?

what cache?  ld and the run-time linker are separate entities and share
no inrofmation.
