g++ errors after upgrading XCode Command Line tools to version 15.0.0.0.1.1694021235

[Carlo Tambuatco]

macOS 13.5.2
package-id: com.apple.pkg.CLTools_Executables
version: 15.0.0.0.1.1694021235

My g++-mp-12 (from gcc version 12) install on macports started giving me these errors compiling 
C++ programs after upgrading my XCode command line tools a few days ago.

Is this something macports will address in a future update? Do I need to reinstall/recompile 
all of macports?
