 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

   File "<ipython-input-1-5977d52fd447>", line 1, in <module>
     from scipy.interpolate import interp1d
   File

 /site-packages/scipy/interpolate/__init__.py", line 150, in <module>
     from .interpolate import *

   File "numpy.pxd", line 155, in init scipy.special._ufuncs
 (scipy/special/_ufuncs.c:9950)
 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?
