Ok, can you give some details what had to be changed?

This will be fixed in Sage 3.2 and a patch is at

Ok, that could be the BLAS or something in LinBox itself. How did you
build ATLAS?

we patch the commentator and that breaks "make check". Should LinBox
pass its make check we can keep on digging.
