py27-scipy: problem importing scipy.interpolate.intrep1d, "numpy.dtype has the wrong size"

[csiebern@…]

I am running macports on a MBP with Lion 10.8.4

I have installed python 27 and the scientific packages (Numpy, SciPy etc.) When trying to import the intrep1d function from scipy.interpolate python returns the following error:

Traceback (most recent call last):
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/IPython/core/interactiveshell.py", line 2731, in run_code

ValueError: numpy.dtype has the wrong size, try recompiling

I have tested and can use Numpy and dtype alone and agree with the error recommendation that the scipy packge should be recompiled.

Can I do this using the macport installer, or will I need to build scipy from source with Xcode and install independent of macports?

Works for me! OS X 10.8.5, Xcode 4.6.2, Build version 4H1003, py27-scipy @0.13.0_1
