[R-SIG-Mac] Fortran on MacOS Sierra

[Ken Beath]

I tried to build frailtypack from source using R 3.3.1 and it failed with the following message (after a ridiculous amount of warnings)

I was going to attempt the build with gfortran 4.2 but haven’t been able to revert back from 4.8

So does it happen with 4.2 and if not, how can I revert back?

If not is this an R problem or the package?
