You're right, i have indeed a dependency problem because of this aur package, acml-gfortran, wich have in it's dependencies gcc-fortran instead of gcc-fortran-multilib
The thing i don't understand is how have i been able to install gcc-fortran with acml-gfortran, without trying to install gcc-libs and discovering the conflict at that time,
and also why the fact that there is a gcc-fortran and gcc-libs update without the corresponding update in the multilib version discover the conflict.
I've commented the aur package, so the maintainer will soon fix the problem, yet i don't understand fully why this conflict have appeared now.
