[R-SIG-Mac] exact versions for mavericks CRAN builds

[Jonathon Love]

hey,

so i found this,

https://cran.r-project.org/web/checks/check_flavors.html#r-devel-macos-x86_64-clang

this lists the configuration for CRAN checks as:

Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn), gfortran 
4.8.2

which is probably the versions used by CRAN for builds.

just posting this in case others are interested in what build 
configuration CRAN possibly uses.

cheers
