New description:

 Following the instructions, including a clean install of Catalina and a
 clean install of Macports, after getting a first round of errors, then
 forcibly deactivating libunwind-headers, the installation of gfortran
 continued until:
 {{{
 --->  Building libgcc7
 Error: Failed to build libgcc7: command execution failed
 Error: See
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc7/libgcc7/main.log
 for details.
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 Error: Processing of port gcc6 failed
 }}}
 I'm happy to send a full log if needed, but I don't want to bog this
 message down with it unless it's necessary.

 Thanks!
