most likely, you switched out the system ATLAS library and now it
crashes in the ATLAS library.

Well, presumably, but not much of an issue. "Simply" reinstalling the ATLAS spkg (with SAGE_ATLAS_LIB set appropriately) and rebuildung every package that depends on ATLAS /should/^TM be sufficient:

$ env SAGE_ATLAS_LIB=/path/to/system/atlas/libs ./sage -f atlas

$ env SAGE_UPGRADING=yes make build

(Note sure whether some Cython extension modules need to get rebuilt/relinked as well, and if so, whether the dependencies are complete in that the above would automatically rebuild them.)
