that shouldn't be necessary if you use the CRAN release since it specifically points to the SDK. If you are compiling your own R you may want to add
CPPFLAGS='-isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include'
which is what the CRAN build uses. FWIW you can always check the current flags at
If the above doesn't address the issue you're seeing, please provide details.
