Roy, 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 https://svn.r-project.org/R-dev-web/trunk/QA/Simon/R-build/conf.el-capitan-x86_64 If the above doesn't address the issue you're seeing, please provide details.
