Actually I discovered it's a small bug in npy_endian.h.

npy_cpu.h correctly detects and sets CPU architecture macros *but* for  
some reason npy_endian.h doesn't handle PPC64 and set big-endian. So,  
npy_cpu.h correctly detects PPC64 as the arch being built for but then  
the endianness setting code doesn't know what to do with it. The AMD64  
build works fine.

I've filed a ticket at http://projects.scipy.org/numpy/ticket/1111 and  
attached a patch there, if you need it.
