Comment (by kencu):

 mesom will always use @rpath during the build for any in-tree library
 references (for running tests, etc, to find the right library) and
 replaces it during install with the full path.

 That's why we have the headache on Tiger and have to patch meson there.

 It's a mechanism at the heart of meson, used on all non-windows os
 versions. They won't be changing it I believe.

 Despite @rpath, this was all working until, I believe, /opt/local/lib
 began being removed from the librsry list so as to avoid adding it to
 DYLD_LIBRARY_PATH.
