Comment (by jmroot):

 You could reinstall whatever ports you have installed with +gcc48 with a
 newer gcc variant. E.g.
 {{{
 sudo port install pgplot -gcc48 +gcc9
 }}}

 But if you have ports installed with +gcc48 in the first place, that
 implies that they were built on an older OS version and you need to follow
 the wiki:Migration procedure.
