If it stills fails, in order to try to reproduce, I would need: 1) emerge --info, and could you also provide: 2) result of: eselect blas show eselect cblas show eselect lapack show 3) which fortran compiler are you using. Thanks. markusle@gentoo.org 2008-04-16 15:12:46 0000 Sébastien, I can reproduce it here on my opteron with -j1 both with atlas and reference. This looks like a linking problem between some C and Fortran routine. Interestingly, -r2 seems to compile so it may well be another one of these issues we had when dealing with the clapack patch.

[I still don't understand what changed between version and I suspect a portage update changing behaviour of some global scope settings] Thanks.
