Compiling atlas may take a long time on fast machine if you don't have arch defaults, though (it takes several hours for my workstation which has two xeon @ 3.2 ghz).
My impression is that using 64 bits OS is still a bit rough, anyway. David _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
