[R-SIG-Mac] Xcode 10.3 and header flles

[Roy Mendelssohn - NOAA Federal]

Hi Simon:

 I am using CRAN release,  recommended CRAN compilers.  Yesterday morning one updated package needed to be installed from source,  worked.  Yesterday afternoon did the update of Xcode (and OSX).  This morning installing a package update from source failed,  couldn't find header files (gee I have seen this before).  Ran the command I put below,  everybody was happy.  It does appear that the update literally deleted the headers.

HTH,

Roy

PS - not trying to build R from source,  just source updates of some packages
