Libgcc12 not working on MacOS Ventura (arm64).

Dear MacPort, I was trying to install the port gcc12 on my MacMini (with M1 CPU), running Ventura OS. I ran into the following error with the dependency port Libgcc12:

You have not really posted enough information to be sure of the issue (you should attach the complete log) but I strongly suspect this is a duplicate of ​https://trac.macports.org/ticket/66457

Here I attach the config.log file generate by the failure of the installation of libgcc12

So yes, it's a duplicate.
