One possible reason (maybe not the only one) for the binary build to need recent (sse2) set of instructions may be this bug on atlas package: http://trac.sagemath.org/sage_trac/ticket/13706 It has the effect of chosing HAMMER architecture (btw, where is this default choice coming from ?) when SAGE_FAT_BINARY is set to 'yes', no matter the value of SAGE_ATLAS_ARCH (which could be older than Hammer). After aplying the basic patch (which should be checked/improved by specialists), sse2 does not appear anymore on sage-flags.txt and the build works on Pentium 3. The request about distros is not to have many distro-specific builds that cost a lot but one autonomous robust non-distro-specific build. You ask for "contributing a buildbot slave machine for building the binaries", is this about buying a machine or about spending time in maintaining a buildbot on an existing machine ?
