[R-SIG-Mac] R , RCPP unsing MACOS ventura

I know that posting a makevars is somehow iffy, but I installed GCC with homebrew and my

~/.R/Makevars

I installed the command line tools with

xcode-select --install

and I installed gcc with homebrew. It works:

Google shows others have had the issue.

Suggestions include...

Uninstall and reinstall command line tools.

��

...following the wisdom of the "homebrew doctor" solves it, i.e. remove and reinstall:

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select �install

���


Rebuild with export SYSTEM_VERSION_COMPAT=1
