bug with numpy.roll

Whenever I try to roll an array with the axis specified, I get a NameError: global name 'prod' is not defined. The full session looks like:

$ pypy
Python 2.7.3 (87aa9de10f9c, Nov 24 2013, 20:57:21)
[PyPy 2.2.1 with GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.2.79)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``why there is no "PyPy 1.4
released" in topic any more?''
>>>> import numpy as np
>>>> a = np.arange(10)
>>>> np.roll(a, 1)
array([9, 0, 1, 2, 3, 4, 5, 6, 7, 8])
>>>> a = np.asarray([[1,2,3],[4,5,6]])
>>>> np.roll(a, 1)
array([[6, 1, 2],
       [3, 4, 5]])
>>>> np.roll(a, 1, 0)
