 This shows that the CLTs are installed, but unfortunately there is a bug
 that sometimes prevents Software Update from noticing that they are
 outdated. You can check the version with pkgutil:
 {{{
 % pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
 package-id: com.apple.pkg.CLTools_Executables
 version: 12.4.0.0.1.1610135815
 volume: /
 location: /
 install-time: 1611851539
 groups: com.apple.FindSystemFiles.pkg-group
 }}}
 If that shows an older version or says that the package is not installed,
 follow ProblemHotlist#reinstall-clt.
