Symliks to add for R 3.1.0 (Mavericks version) to run and compile packages

R symlinks

After you have installed gfortran from homebrew using 
$ brew install gfortran

After installing R... add the following lines to ~/.R/Makevars
FC = /usr/local/bin/gfortran
F77 = /usr/local/bin/gfortran
FLIBS = -L/usr/local/Cellar/gcc/4.9.2_1/lib/gcc/4.9 -lgfortran -lquadmath -lm

and openblas using
$ brew install openblas
$ ln -s /usr/local/Cellar/openblas/0.2.13/lib/libopenblas.dylib /Library/Frameworks/R.framework/Libraries/libRblas.dylib

make sure all the appropriate versions are correct! These were the versions I have when I created this gist.
