Comment (by nh2):

 {{{
 nh2:           and in the case where the "hinted" so location doesn't
 exist, what does it do, does it then search the search paths?
 sphalerite[m]: no. It's not a hint, it's "the library is here". It's "if
 the library is not here this program will not run."
 nh2:           hmm OK. So that approach only works if you really know
 ahead of time where the lib will be
