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?
