[R-SIG-Mac] [External] Re: Xcode 10.2.1

[Roy Mendelssohn - NOAA Federal]

Yes that is where I found the command.  I would add though that I had done that for Xcode 10.2.0, and appears that when you install the new versions that the installer actually deletes the headers at that location.  At least that is what happened to me when I updated to Xcode 10.2.1.  So people should be aware of this.  Each update may delete the headers.

In the previous thread,  Simon was looking into possibly changing where the R tools look for the headers, but that sort of thing is beyond my pay grade.
