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are installed, but unfortunately there is a bug that sometimes prevents Software Update from noticing that they are outdated.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.

AFAIK, this has been fixed for quite a while.

Are you still seeing the issue?

Not currently using 'gcc9'.

Great, glad to hear it's no longer an issue!
