Ok, I didn't look too closely and then didn't write this email

pni == sse3, so no surprises here. But at least on my end there are no
plans to build an SSE only, i.e. no SSE2 only binary for 32 bits since
those CPUs are exceedingly rare and accomplishing this is a lot of
work and other tasks I have take way higher priority. So the only
real option is to build from sources inside the VMWare machine.
