A recent Xcode update has removed the CLT installation receipts, so the Apple update system is no longer aware it is still installed, and the MacPorts checks as performed by the xcode_workarounds/cltversion PGs for the CLT versions are unable to determine the version installed.

It would be better to properly fix the installation to make sure the CLT version matches the Xcode installation (which currently the PGs cannot do).

Oh right. Sorry... I've updated the 10.15 worker to Xcode 11.3.1 and reinstalled the CLT. Hopefully that solves it for now.
