The port chose to use Xcode clang, which is:

Xcode v13.4.1 (13F100)
Apple clang version 13.1.6 (clang-1316.0.21.2.5)

so apparently that's not enough. See also #73910 for another situation where the codex port picked a not-enough compiler.

This failure occurred after expending 4 hours of build time, so it's important for the health of our build system to fix this so that the port can either build or fail immediately with an error.
