Comment (by tglsfdc):

 I found out by accident that the failing compilation succeeds if I just
 invoke it manually rather than via "port install".
 That is:
 {{{
 $ sudo port install python39
 ... wait for it to fail ...
 $ cd
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_python39/python39/work/Python-3.9.7/Mac/PythonLauncher
 $ sudo make
 ... ignore assorted warnings ...
 $ cd
 $ sudo rm -rf /Applications/MacPorts/Python\ 3.9      # clear out detritus
 from previous failure
 $ sudo port install python39
 ... succeeds!
 }}}
 This makes basically no sense to me, but I know nothing of the internals
 of MacPorts.
