Comment (by giovannicantele):

 I'm going to attach the log of
 {{{
 sudo port clean openblas
 sudo port install openblas +gcc10
 }}}

 What is a bit strange is that everything was working perfectly until few
 days ago, and what broke everything was the {{sudo port selfupdate}} of
 yesterday or the day before yesterday.
