R docker failing to download el-capitan.dmg

language: r
os: osx

unable to connect to http://coudert.name/software/gfortran-6.1-ElCapitan.dmg

Same problem here:


It seems that the url used by curl during installation of gfortran has changed there: https://www.coudert.name/software

I don’t known if it is possible to correct this in .travis.yml …
