Error when using the python module numba

Error when using the python module numba

I have installed LLVM 3.2 and all dependencies of numba (except Meta):
LLVM 3.1 or 3.2
llvmpy (from llvmpy/llvmpy fork)
llvmmath
numpy (version 1.6 or higher)
Meta (from numba/Meta fork (optional))
Cython (build dependency only)
nose (for unit tests)
argparse (for pycc)
I installed LLVM 3.2 and llvmpy according to the instructions on this page
https://github.com/llvmpy/llvmpy. All the other python modules were
installed using pip:
sudo pip install --upgrade module_name
Next I tried the numba examples on this page:
http://jakevdp.github.io/blog/2012/08/24/numba-vs-cython/. I stored both
pairwise_python and pairwise_numba in a file named performance.py. Then
when I run
from performance import *
in IPython I get the following error:
---------------------------------------------------------------------------
AssertionError Traceback (most recent call last)

212 return_type = None
213 argtys = []
AssertionError: <function pairwise_numba at 0x4b61a28>
And I am not able to use pairwise_python nor pairwise_numba. How can I get
this to work?
