Comment:

 You did not mention here what version of Xcode you use, but you mentioned
 elsewhere (in #61321) that you use Xcode 12.4 and the compiler version
 shown above (clang-1200.0.32.29) confirms that.

 The log above shows that it is trying to use MacOSX11.0.sdk, which does
 not exist in Xcode 12.4.

 Please attach the main.log so that we can see whether MacPorts base is
 specifying the wrong SDK to the build (if so, that would seem to be #61866
 though it was supposed to have been fixed already) or whether the build is
 finding the wrong SDK on its own.
