 Replying to [comment:2 lukaso]:

 -x86_64 /bin/zsh`. So yes, this is an Arm64 machine.

 Then the next question is: why are you doing this? This is not a normal
 way to use MacPorts.

 worked:

 Right, it works if you use `/usr/bin/clang` as the compiler. The failing
 tests are not using `/usr/bin/clang` as the compiler; they're using the
 empty string.
