Python 3.2 64 Bit Numpy install - LaPack bug

I have python latest 3.2.3 64bit installed on my windows 7 laptop. I am trying to use pip to install packages.

However, I get a Lapack error.

C: \ Users \ Renshaw family \ build \ numpy \ build \ py3k \ numpy \ distutils \ system_info.py: 13 54: UserWarning:

Lapack (http://www.netlib.org/lapack/) sources not found. Directories to search for the sources can be specified in the numpy/distutils/site.cfg file (section [lapack_src]) or by setting the LAPACK_SRC environment variable. 

warnings.warn (LapackSrcNotFoundError. doc )

I went to the numpy download site to install via exe, however the site does not have 64-bit builds for 3.2. Python (x, y) stays only at 2.7.

I found unofficial assemblies and downloaded numpy-MKL-1.6.2.win-amd64-py3.2.exe, is it currently the only solution to install unofficial assemblies?

On Windows, there is no official way to set 64-bit 64-bit bits. This is due to compilation issues on this disc. However, there are unofficial releases using Intel MKL as a replacement for Lapack. Another option is to use a 32-bit Python installation. But you will be amazed at the 2 GB memory limit.
