 Replying to [comment:3 michaelld]:
 > The error in `config.log` is `clang: error: invalid version number in
 'MACOSX_DEPLOYMENT_TARGET=11.1'`, which leads me to believe that your
 Xcode install isn't the correct one

 This error means that the clang in your Xcode ''or'' in your Xcode command
 line tools—whichever one this port is using—is not compatible with macOS
 11. In this case, this port is using the Xcode command line tools, so it
 is the version of the Xcode command line tools that you have installed
 that is not compatible with your OS.

 Please make sure you are using [wiki:XcodeVersionInfo a version of Xcode
 that is compatible with your OS version]. Xcode 12.2 and later are
 compatible with macOS 11 Big Sur, but the latest Xcode 12.x is
 recommended. That's currently Xcode 12.5.

 You ''must also make sure'' that if you install the Xcode command line
 tools, its version matches your Xcode version. Due to [wiki:ProblemHotlist
 #reinstall-clt a bug in macOS], Software Update may not offer to upgrade
 the Xcode command line tools for you, so do it manually by following the
 instructions in the wiki page or by
 [http://developer.apple.com/download/more/?=Command%20Line%20Tools
 downloading it from Apple].
