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

That probably means that #:substitutable? should be propagated–i.e.,
that anything depending on ATLAS should not be substituted.

Thanks for investigating!
