David says this is due to a stray old file (see earlier post), you need to
clean out the previous numpy installation.

It is the odd long double of PPC, also reported earlier. It should probably
be marked a known fail on PPC. If David or a developer had a PPC it might
could be worked out. OTOH, long double on PPC isn't any sort of IEEE so,
strictly speaking, we don't support it.
