As a result we have the following situation: 1. hydra builds a version of ATLAS optimized for its CPU locally. 2. 'python-numpy-bootstrap' and co., on some architectures, probably get an incompatible version of ATLAS and therefore fail to pass some tests. You can check in the build log of 'python-numpy-bootstrap' that ATLAS, despite the flas, is substituted (no local build on the slave). At some point we should fix the support for '#:substitutable?' on hydra (or the upcoming 'guix publish'). Regards, Fede
