Is there anything I can do to help track down this slightly wrong  
behavior?

Also, in general, should I be building/installing other blas/atlas/ 
lapack-stuff libs on the mac to get numpy in optimal shape? Or  
(modulo wrong behavior) should what numpy provides and what VecLib  
provides be all I want?

thanks,

Zach
