[R-SIG-Mac] Issues with rj (requirement for StatET) since Mojave/3.5.1 update

[Roy Mendelssohn - NOAA Federal]

Check that you have the latest version of the clang compiler from the r-mac site.  I believe the present version supports -fopenmp, previous version did not.  If not,  I can point you to a different link to download the compiler, but I think using the officially approved versions the cleanest solution.

HTH,

-Roy
