lapack-atlas doesn't do anything. Here's what the emerge -C output shows. No wonder it wasn't working for me. -(/usr/lib:$)-> emerge -C lapack-atlas app-sci/lapack-atlas selected: 3.6.0 protected: none omitted: none >>> 'Selected' packages are slated for removal. >>> 'Protected' and 'omitted' packages will not be removed. >>> Waiting 5 seconds before starting... >>> (Control-C to abort)... >>> Unmerging in: 5 4 3 2 1 >>> Unmerging app-sci/lapack-atlas-3.6.0...

Hi David. Thanks for the report. Try rebuilding blas-atlas or blas-reference, whichever one you have active (I suspect blas-atlas). Also make sure it is really active - run blas-config -p or even just rerun blas-config to set the one you want. This should fix it. I weirdly just had the same situation. I suspect new toolchain has something to do with it. I'd issue a new revision just to bump these libs on everybody, but these packages are still in the works. Well, more precisely waiting on toolchain and fortran.eclass to stabilize. George
George, The problem was related to lapack-atlas not being able to see libcblas because it was installed/symlinked in /usr not /usr/lib. It's a blas-config problem
