Comment (by nhchan):

 I have the same issue, and would like to add my `main.log` to the
 collection here.

 For context, I am running macOS 11.2.3, MacPorts 2.6.4. Also, running
 `pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | grep version`
 gives me `version: 12.4.0.0.1.1610135815`, although I still get the
 following warnings:

 {{{
 Warning: The macOS 11.2 SDK does not appear to be installed. Ports may not
 build correctly.
 Warning: You can install it as part of the Xcode Command Line Tools
 package by running `xcode-select --install'.
 }}}

 I have re-installed Xcode and Command Line Tools at least 3 times,
 including directly downloading the installers from Apple's Developer site.
