Hi Thomas, sorry I don't have the expertise to help you with your
question.  I am wondering if you are using one of Apple's new G4
machines?  I'm curious about the floating point performance of those 
chips.  If you ever get Numpy working, I have a routine that I use for a
benchmark, a Norton-Summerfeld ground (antenna) simulation routine that
I could send to you.  The record for me is 120s on a P4 1.8Ghz at work,
but I'm sure the new Xeons would beat that, and maybe the new Athlons. 
My 1.2Ghz DDR Athlon is much slower than the P4, but the clock speeds
are so much different.  Rob.
