Probably you installed NumPy for python3.2:

http://packages.ubuntu.com/precise/python3-numpy

Probably you built 3.3 from source or installed from the deadsnakes
PPA. Install the NumPy build dependencies and then build/install via
pip:

    $ sudo apt-get build-dep python3-numpy

You might want to `pip install numpy` in a virtual environment
(pyvenv-3.3 or virtualenv) for testing before pip-3.3 installing to
/usr/local. Or you could always use virtual environments and build a
wheel package for subsequent re-installations.
