Well, a little bit more of digging, thinking, googling and I think I
know what to do.

I have two stages where I must be able to compile, link and run code
using the lib:
A. conftest code at configure time
B. the build product at runtime (of course)

B is working by means of autoconf/libtool.
A is giving me problems because afaict as described I must inject -R
or -rpath depending on the environment.

Presumably I should be able to use LD_LIBRARY_PATH instead to solve A,
which afaict should be quite portable.

Correct? Portable?
