Hi, depending on what we have installed, there's the need to replace 'atlas-lapack-base' by 'cblas', 'lapack' and 'openblas'. My install's dependency chain needs it for packages such as 'blender' and 'gimp' (all from official repositories), resp. without having 'sagemath' installed 'openblas' seemingly could be replaced by 'blas' [1], too. However, there's seemingly the need to install 'cblas', 'lapack' and 'openblas' or 'blas' first. Perhaps this should be mentioned by the news at https://www.archlinux.org/ and by https://lists.archlinux.org/listinfo/arch-announce.
