Comment (by jasonliu--):

 I was recently also hit with this problem in a port that I am trying to
 make a Portfile for, where the upstream devs are providing some portions
 of their library as pre-compiled binary blobs, which have weakly linked
 dependencies. It looks like one workaround is to use
 {{{install_name_tool}}} and setting the weak dependency to something that
 is guaranteed to exist, such as the root folder ({{{/}}}).
