I tested ubuntu and freebsd cbc solvers from their repositories. Miplib enlight_hard.mps solved in 400 seconds with ubuntu and in 68 seconds with freebsd. And neos-957323.mps was another one that was solved much faster with freebsd cbc. Both cbc solvers were v 2.10.7. Why so huge difference?
With Arch linux I installed coin-or-cbc and nauty from their repository (pacman -S coin-or-cbc nauty) but how can I tell if that cbc is really using that nauty?
