No, it doesn't. You must be using some other binary that the official CRAN one (http://cran.r-project.org/bin/macosx )
Our binaries only use standard Apple compilers (from Xcode - in recent OS X versions you can use xcode-select --install on the command line to install) plus a GNU Fortran that you can download from CRAN.

I you use brew, then you're on your own and you should refer to their support. Our builds do not require brew (or any other 3rd party build system).
