The scipy and numeric docs don't know anything about the upcoming new Gentoo scheme, where liblapack can be a front for libatlas or any other library that implements lapack. That's actually the beauty of the new system: even if you have a program which in its configure scripts does not know anything about alternate lapack implementations, its still possible to use it with ATLAS. But if you're building SciPy on a non-Gentoo system (or on the the current Gentoo, i.e. before the switch), then it's obviously necessary to include the correct atlas info. Peter
