[R-SIG-Mac] Tools Update for R3.5?

[Roger Koenker]

Maybe this would provide a little more explicit information about what is going wrong:

/usr/local/clang6/bin/clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG   -I/usr/local/clang6/include   -fPIC  -Wall -g -O2  -c init.c -o init.o
In file included from init.c:1:
/Library/Frameworks/R.framework/Resources/include/R_ext/RS.h:34:11: fatal error: 'string.h' file not
      found
# include <string.h>            /* for memcpy, memset */
          ^~~~~~~~~~
1 error generated.
make: *** [init.o] Error 1
