Comment (by mascguy):

 This failure is also occurring on macOS 10.12, so it's not limited to Big
 Sur:

 [https://build.macports.org/builders/ports-10.12_x86_64-builder/builds/135633/steps
 /install-port/logs/stdio]

 When recently setting up a macOS 10.12 VM for testing, I saw the same
 issue. After a few minutes of head-scratching, I tried launching the Xcode
 IDE once, to allow the one-time Xcode setup to occur. After that, it
 worked.

 Does anyone know precisely what Xcode is doing during that setup, and
 whether it can be initiated from the command-line?
