sci-libs/gsl-1.15.ebuild will pull eselect-cblas during emerge, which prevent it from installing on machines with newer sci-libs/lapack-reference and/or sci-libs/blas-reference. Reproducible: Always
Created attachment 360540 [details, diff] remove_eselect-blas.patch In this patch, most of the eselect-cblas related lines are committed out.
(this is not a regression over current stable)
Please use newer gsl like 1.16. Mixing old and new numeric lib stuff doesn't work.
