This is strange... I definitely was able to build it with numpy 1.6, otherwise how could I have made the packages? I do see the same problem on precise, but nowhere else. This all does sound like a nasty numpy compatibility thing, but it is not at all clear what is going on. I'll have to take a closer look. Cheers, Tiago -- Tiago de Paula Peixoto <[email protected]>
