NumPy won't upgrade from 1.5.1 to 1.6.2 on OS X 10.7

Question

I am attempting to update/upgrade my NumPy, but am failing. I think I might have multiple versions of NumPy installed in different directories, but python by default imports an old one. Any help?

Here's where my Python is:

Gonzo-vs-Kitties:~ brian$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python

Here's the version that Python imports:

Gonzo-vs-Kitties:~ brian$ python
Python 2.7.3 (v2.7.3:70274d53c1dd, Apr  9 2012, 20:52:43) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> print numpy.__version__
1.5.1
>>>

Now I use easy_install to upgrade NumPy:

Gonzo-vs-Kitties:~ brian$ sudo easy_install --upgrade numpy

Even after I upgrade, NumPy is still the old version:

>>> import numpy
>>> print numpy.__version__
1.5.1
>>>

This is my sys.path:

>>> print sys.path

Any ideas?

Check the path of your numpy package:

import numpy
print numpy.__path__

And check whether it is the one you just installed.
