[Zope] python locally compiled or binary distribution

I just build Python 2.1.3 locally and ran pystones and compared it to the
distribution binary version. I did not tuning and chose no special
options. On a dual processor 2100+ Athalon I got:
distribution: 20833.3 pystones
local build: 20408.2 pystones
I can up the level of optimization a bit (I think it defaults to -O2) but
this seems a bit off from your results. What flag settings did you use?
