Simon,

Thanks for the reply.  As of yesterday, everything seemed to be working OK 
without any ~/.R/MakeVars file. viz, I can compile packages using the 
binary you provide for R-3.4.0.  Also, I can configure, make, and make 
check R-devel using the clang4 you provide.

I can't say what is different now from before.  I just updated pcre and 
added pkg-config, java JDK, and cairo.  I recently re-installed command 
line tools, but I have had these `forever'.

Anyway, all is now well.

Thanks,

Chuck
