You might try locating the binary that executes, then running ldd against
it, e.g.: ldd somebinaryexecutable, this will show a list of libraries it
was built against. ldd -a somebinaryexecutable will show a little more info
which may be useful if you find that a libmap.conf entry may be useful as a
temporary work around.
If you use binary package management (pkg), possibly there is an error in
how they were built and a PR with this information would be helpful to the
powers that be. I only build through ports and know next to nothing about
I seem to recall that the huge Qt monolithic was broken up into many pieces,
and perhaps it's one, or more, of the other pieces that are subdependencies
of a Lynx dependency and that's where the mismatch is. So maybe Lynx was
built against the right libs but some other dependency was still linked
against a crufty old one.
I don't consider libmap.conf to be a fix, per se - better to find the items
linked against the old lib(s) and rebuild it against the new lib(s) imho.
