gimp-app fails to build after sudo port selfupdate with error:

Error: Target org.macports.build returned: shell command failed (see log for details) Log for gimp-app is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_aqua_gimp-app/main.log Error: Unable to upgrade port: 1

Tried some of the suggestions in #26747, i.e.:

sudo port clean --all gimp-app sudo port selfupdate sudo port sync sudo port upgrade --force installed

main.log (full log attached) contains at the end:
