Oh. Actually, slaves do not use substitutes at all, but they receive missing store items from hydra.gnu.org when builds are offloaded. So I suppose they receive something built on hydra.gnu.org, which may be incompatible. > At some point we should fix the support for '#:substitutable?' on hydra That probably means that #:substitutable? should be propagated=E2=80=93i.e., that anything depending on ATLAS should not be substituted. Thanks for investigating! Ludo=E2=80=99.
