libgcc11 failed build failed on macOS 13.0.1

[André-John Mas]

TL;DR Found the solution: uninstall gcc11, since it turned out to be broken

In depth:

I just ran `port rdeps youtube-dl` and apparently nothing depends on gcc or libgcc. 

Reading the messages a bit more I missed, or ignored, the following line:

  "Found 1 broken port, determining rebuild order"

Based on having tried everything else I decided to uninstall gcc11 and try again. It all 
worked. This would suggest Macports was doing a post install step to fix the
broken ports, but it wasn't clear that it was unrelated to the port being installed.

Since youtube-dl didn't have the libgcc11 dependency in its tree, it helped indicate the
issue was probably elsewhere - thanks Ken.

Just for for anyone searching in the future full output on the CLI, for the build

--->  Found 8 broken files, matching files to ports

You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt: gcc11 @11.2.0
