Hmm, what is your exact CPU architecture? I.e. the output from "cat /
proc/cpuinfo"? Reasons for the crash might be
a) a corrupted download (unlikely)
b) ATLAS vs. your CPU issue

Probably the easiest thing to get rid of the problem would be to
compile from sources. You can also switch to a system ATLAS by
following the FAQ entry "QUESTION: I downloaded a Sage binary and it
crashes on startup with Illegal instruction. What can I do?" - see
http://wiki.sagemath.org/faq
Let us know if that works.
Cheers,
Michael
