Comment (by cjones051073):

 You shouldn't be using libgcc9 for anything any more. Only (lib)gcc10 or
 newer should be use on 10.14.

 You need to though manually, yourself, identify which ports are still
 using libgcc9 on your system and manually reinstall them using newer
 variants of gcc. Run

 {{{
 port list installed | grep gcc9
 }}}

 and then, for each of those ports manually uninstall them and reinstall
 using the new default variants, which will be using (lib)gcc12 instead.
