sudo port upgrade outdated crashes with MacOS 10.13 High Sierra

[manulcaux]

I upgraded my Mac OS to 10.13 High Sierra I upgraded MacPort downloading and running the MacPorts-2.4.1-10.13-HighSierra.pkg When then running sudo port upgrade outdated, I get this error :

[macp2052:~] caux% sudo port selfupdate Password: ---> Updating MacPorts base sources using rsync MacPorts base version 2.4.1 installed, MacPorts base version 2.4.1 downloaded. ---> Updating the ports tree ---> MacPorts base is already the latest version

The ports tree has been updated. To upgrade your installed ports, you should run

port upgrade outdated

In the file /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc48/gcc48/main.log

I see

gcc48 is not supported on macOS High Sierra and newer

Is this definitive ? Meaning the software I have needing gcc48 to compile will not be working anymore ?
