 check to see what is installed at that time, and decide what to use based

 making it possible for the user to request that the Xcode clang is
 selected if it's installed. Better yet, do this by default - use Xcode
 clang if it's installed, unless the user explicitly requested something
 else.

 Xcode’s clang is already part of the check. Nothing needs to change in
 this regard.

 variant, even if it's a devel version.
