Huh, that's wild.

Is that one installed cleanly? The bone-headed approach would probably be to reinstall all three of these packages (opendmarc, libopendmarc2 and libspf2-2) just in case one of them is corrupted or something. If it were me, I'd use nm(1) on the various shared libraries and track down where this symbol is coming from. That's a lot more effort.
