And on my Mac:
OS-X 10.4.*, PPC, universal python 2.4.3:
>>> import numarray as na
>>> na.__version__
'1.5.1'
>>> bbb=na.zeros((2,3,3), na.Float32)
>>> bbb[0,:,:]=1
>>> bbb[1,:,:]=2
>>> ccc=na.transpose(bbb,(1,0,2))
>>> d=na.array([[1,0],[0,1]])
>>> na.dot(d,ccc)
array([[[ 1., 1., 1.],
[ 2., 2., 2.],
[ 1., 1., 1.]],
[[ 2., 2., 2.],
[ 1., 1., 1.],
[ 2., 2., 2.]]], type=Float32)
