Comment (by robwgla):

 I found a workaround:

 0. completely removed MacPorts

 1. completely removed Command Line Tools

 2. reinstalled Command Line Tools via `xcode-selecet --install` (installed
 `macOS11.1.sdk`)

 3. reinstalled MacPorts

 4. updated MacPorts `sudo port selfupdate`

 5. started reinstalling “my ports”

 6. SDK warning still occurs!

 7. pointed Command Line Tools manually to
 `/Library/Developer/CommandLineTools` via `xcode-select -s ...`

 8. SDK warning still occurs!

 9. made link `macOS11.2.sdk` pointing to `macOS11.1.sdk`

 10. all “my” installs and builds without flaws! No warnings, no build
 errors for `R`.

 11. `cotave` failed:

 Maybe my findings are of some help.
