 OK. Good to know. It's either lazy or pragmatic ... IDK which! One can
 always set `DYLD_LIBRARY_PATH` to test the in-build library; this is what
 CMake does by default rather than use `@rpath`. "To each" I guess ...

 > 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.

 Hmmm ... interesting conceptual observation ... I'm pretty sure the
 `@rpath` usage would result in a defective GIR file regardless of our/my
 GO-I tweaks thus far ... I'll test this to verify.

 I'll also investigate if there's way to split the library paths so-as to
 provide a list to the `shlibs.py` scripts to less-dangerously work around
 this issue.
