Xcode 15 issues - my temporary workaround

[Carlo Tambuatco]

So, if I upgrade to macOS Sonoma, and I have to follow the
migration process for upgrading macOS and macports, would the process
detailed by the OP work but instead of renaming /opt/local and
/Applications/Macports I should install ld64, then edit /opt/local/bin/ld
to add -ld_classic option before installing gcc12 and reinstalling all my
other ports?
