[sage-support] Re: 3.4 binary for Fedora 10 crashes
Does that mean that also I cannot compile sage myself on a non-sse3 machine (like my old amd64)? When I try I get Illegal instructions but not sure if its the cpu or something with the dependencies.

When I try I get Illegal instructions but not sure if its the cpu or something with the dependencies. The problem is ATLAS build by Sage, it uses SSE3 instructions. If you build from sources on a non-SSE3 CPU ATLAS will not use SSE3 instructions, so building from source should work.
