[Numpy-discussion] ANN: NumPy 1.8.0 release.

[xavier.gnata at gmail.com]

On ubuntu 13.10 with the following packages installed:
libopenblas-base
libopenblas-dev
liblapack-dev
liblapack3

site.cfg:
[DEFAULT]
library_dirs = /usr/lib
include_dirs = /usr/lib/openblas-base
[openblas]
libraries = openblas
library_dirs = /usr/lib/openblas-base
include_dirs = /usr/lib/openblas-base

I get this error when I try to import numpy1.8:

/usr/local/lib/python3.3/dist-packages/numpy/__init__.py in <module>()
     151         return loader(*packages, **options)

What's wrong?
