 |I very much disagree.  We have had bug reports as well as cases of our
 |own because a new compilation that you want to test picked up
 |previously installed versions of the libraries (usually an older
 |version).  The reason for doing so previously was because we installed
 |the libraries in non-standard locations by default.

That unpuzzles me a little bit -- this behaviour did exist.  Good.

 |Since OpenSSL 1.1.0 and on is installing in standard locations by
 |default, we don't have to use these mechanisms for a default build.
 |With that, we realised that choosing to use DT_RPATH, DT_RUNPATH (they
 |are different) or whatever isn't really our decision to make, but the
 |decision of the packager or the individual user, so we've handed the
 |decision to you. 
 |
 |For the GNU toolchain, I'd recommend configuring with something like
 |this (from memory, I might be fuzzy in the details):
 |
 |    -Wl,--enable-new-dtags -rpath '$(LIBRPATH)'
 |
 |LIBRPATH is a convenience Makefile variable that gets correctly set to
 |the configured shared library installation directory, meant for
 |exactly this sort of situation.

The latter (DT_RUNPATH) does not overwrite $LD_LIBRARY_PATH, yes,
when i reported the dynamic link test failures a while back i have
seen that and also added support for this new linker flag to my
software.  It is i think off-topic that now new environment
variables come up that makes me wonder why the LD_PRELOAD ..
DT_RPATH .. LD_LIBRARY_PATH chain has ever been declared
deprecated.

LIBRPATH i did not know about yet, thanks for the pointer, i will
read about it.
Yes, i mean, i just didn't know this, it is not mentioned anywhere
(i think that would well be worth in entry in INSTALL), and
i really would have sworn that it worked in the past.

Thank you, and
Ciao!
