[R-SIG-Mac] Xcode

Hey, I have a question about including the R framework in a file. When
I attempt to use:

#include <R/R.h>

And compile I get the following error:
/Library/Frameworks/R.framework/Headers/R.h:40:21: error: Rconfig.h:
No such file or directory
/Library/Frameworks/R.framework/Headers/R.h:41:57: error: R_ext/
Arith.h: No such file or directory
/Library/Frameworks/R.framework/Headers/R.h:42:50: error: R_ext/
Boolean.h: No such file or directory
/Library/Frameworks/R.framework/Headers/R.h:43:50: error: R_ext/
Complex.h: No such file or directory

What am I doing wrong?

Thanks!
Adam
