[R-SIG-Mac] Choosing between Snow Leopard and Mavericks builds

In case it helps other users of the Mavericks build: The instructions for installing the gfortran binaries (<http://r.research.att.com/libs/gfortran-4.8.2-darwin13.tar.bz2>) linked to at <http://cran.r-project.org/doc/manuals/r-release/R-admin.html#OS-X> are to be found here <http://r.research.att.com/libs/>. It took me a little digging to find these instructions; I guess I had been spoilt by the gfortran-4.2.3.dmg installer available for the Snow Leopard build.
While I generally install binary packages, I was dabbling with RcppArmadillo and, while the binary version of this package installs fine, it doesn't work without the right build environment.
(Before discovering the instructions at http://r.research.att.com/libs/, I tried using the gfortran-4.8.2 I had obtained from elsewhere, but it was not where R expected to be and I needed to set FLIBS in ~/.R/Makevars to get it to work for me.)
