 matching version of the Xcode command line tools. There is (or was) a
 macOS bug that prevents macOS from automatically updating the command line
 tools so you have to do so manually.

 Hi,

 I am now having the issue with not finding the tools on a Monerey system
 with Xcode 13.1 - I did not experience this with Big Sur.

 I tried to follow that procedure (manual installation of the Command Line
 Tools) as outlined for the issues with Big Sur, however the tools are only
 available tp those with an Apple Developer subscription.

 On one device I can see the command-line tools/SDKs under the path used by
 the Release version of the SDK but I get the Command-Line Tools not found
 for some packages (not all). I have used Xcode-select and scrub to check
 the settings and they are all correct for the Release version of Xcode
 13.1
