Attached patch fixes this (in an admittedly slightly crude way) for me.

Created attachment 656058 [details] build.log
Upstream played the ball back into our court: > I checked the build system. Our FindPackage(LAPACK) does already search > for the blas libraries. So maybe you are using a slightly different name > of the BLAS library (other implementation) so that CMake does not pick > up this variant. So the easiest way to fix would be to update > CMakeModules/FindLAPACK.cmake for this BLAS variant. Gentoo removes that FindLAPACK.cmake file during src_prepare, probably because a file of the same name is provided by CMake itself.
Upstream further explained that /usr/share/cmake/Modules/FindLAPACK.cmake should actually search (and make the application link against) both LAPACK and BLAS. For some reason this does not happen on my system / Gentoo. I am investigating.
Please reopen if this still occurs.
