Well, I tried to let the install to build ATLAS, but it got stuck at 
downloading the atlas package as my machine is behind firewall.
So I manually downloaded the atlas-3.10.2.tar.bz2 and tried to build it.
But when I tried to build atlas, I got error:
ERROR: enum fam=3, chip=2, model=85, mach=0
make[3]: *** [atlas_run] Error 44
make[2]: *** [IRunArchInfo_x86] Error 2

What should I do?
