Comment (by ryandesign):

 See the code in `mportinit` in [browser:macports-
 base/src/macports1.0/macports.tcl] which simply does:

 {{{
     if {![info exists macports::macosx_sdk_version]} {
         set macports::macosx_sdk_version $macosx_version
     }
 }}}

 MacPorts assumes that an SDK exists whose version matches the macOS
 version. This has not been guaranteed to be the case for many years, as
 Apple has adopted the practice of including only the then-most-recent SDK
 in Xcode, even when that version of Xcode still works on the previous
 version of macOS.

 Maybe MacPorts should be smarter about this and should set the SDK version
 variable to whatever SDK exists in the user's Xcode, even if that does not
 match the OS version.
