Right, but in my case my build directory structure exactly mirrors the
deployment directory structure, precisely so that RPATHs work both in
development and when deployed to production and I don't need to mess
around with LD_LIBRARY_PATH.

The link succeeds if there is some other e.g. in another
directory in LD_LIBRARY_PATH, even though that's *not* the one that
will be used at run-time.

Ah, so it "works" with gold because it doesn't do the check.

It seems this isn't a bug, so I'll use -rpath-link in addition to
-rpath so the library will be found at link-time.

Thanks for the quick response.
