The problem with not providing these binaries is that they are at the
bottom of everyone's stack, so a delay in numpy holds everyone back.

I can't find completely convincing stats, but it looks as though 64
bit windows 7 is now the most common version of Windows, at least for
Gamers [1] around now, and it was getting that way for everyone in
2010 [2].

It don't think it reflects well on on us that we don't appear to
support 64 bits out of the box; just for example, R already has a 32
bit / 64 bit installer.

If I understand correctly, the options for doing this right now are:

1) Minimal cost in time : ask Christophe nicely whether we can
distribute his binaries via the Numpy page
2) Small cost in time / money : pay for licenses for Ondrej or me or
someone to install the dependencies on my Berkeley machine / an Amazon
image.

Ralf : I suppose we qualify for the free licenses you referred to
earlier ?  [3] .  I guess that covers us for the Numpy build?  Then
it's only a question of paying for ifort licenses when it comes to do
the Scipy build?

So, if the cost of option 2 is too high, how about option 1?

Cheers,

Matthew
