Exactly.

It is a fact that some projects (at least some of mine) have been using
that idiom, because that’s the Libtool way to say “hey, load this
particular file, not one that may be found in the search path.”
See, for example,
<http://git.savannah.gnu.org/cgit/gnutls.git/tree/guile/pre-inst-guile.in>.
So the goal is to keep that working.
Ideally, I would accept any solution that (1) gets rid of the
LD_LIBRARY_PATH export, and (2) can be shown with strace to preserve the
extension search order.
How does that sound?
(BTW, the above message was followed-up at

Thanks,
Ludo’.
