I don't follow.

If a shared library A needs another shared library B to load, then it
needs to set RPATH (however that is spelled on systems that are
Different) for the path where B is.

When a program links with A, it needs to set RPATH to fine A.

I can see why /usr/local/lib no longer being in a default search path
would cause this to be noticed, but surely /opt/pkg/lib and /foo/bar/lib
were never there, so this seems like a bug fix.
