Comment:

 Worked for me:
 {{{
 % port -v installed git
 The following ports are currently installed:
   git @2.29.0_0+credential_osxkeychain+diff_highlight+doc+pcre+perl5_26
 (active) platform='darwin 19' archs='x86_64'
 date='2020-10-24T17:45:36+1100'
 }}}
 Without the full log, it's not clear whether an -isysroot flag is not
 being specified or if it's being specified and lost.
