[I think that something like this happened once before, a library was
there, but "invisible."]

I am running Xephem, an astronomy program written in Motif. It has
libXm.so.4 as a dependency. libXm.so.4 is in /usr/lib, as a symlink to libXm.so.4.0.4, but Xephem can't find it. I tried to uninstall and
reinstall the library, but that would have removed a swag of apps,
including Cups and Xephem itself. It worked in the past day or so. I
ran "sudo ldconfig" as a precaution, but that may no longer be relevant
in the systemd world. Rebooting had no effect.

Is there a reason why this happens?

Two immediate silly things come to mind.
Is it permissions or is /usr/lib in the $PATH.

Naturally, I checked both those. My next thought is that libXm.so.4.0.4
won't work in this program (the reason why I have always advocated using
only Mageia RPMs.) I am running Cauldron, for other reasons. 7.1
Official doesn't have the problem. That suggested that maybe there was a recent update of the library, but the Changelog shows that there wasn't
one. I could try recompiling xephem from the tarball.

Can you please give me the sig line that pulls in this info? BitTwister
gave it to me long ago, but I have lost it.

That is not a line. it is a few lines in a script usually executed
during login.

BitTwister gave it to me long ago, but I have lost it.

Bits has considerable elaborated the sig line command these days but I
still use the original dropped into ".bash_profile"

You can also run it with "strace". If, unlike me, you can follow the
output and see if it finds the library.
