_path.so: undefined symbol: PyArray_API


I'm trying to compile numpy/scipy and matplotlib (I did it N times without any problem).
Numpy and scipy are ok (.test() is fine).
However, from pylab import * fails with way:

/usr/local/lib/python2.6/dist-packages/pylab.py in <module>()
----> 1
       3 from matplotlib.pylab import *
       4 import matplotlib.pylab
       5 __doc__ = matplotlib.pylab.__doc__

/usr/local/lib/python2.6/dist-packages/matplotlib/pylab.py in <module>()
     204 silent_list, iterable, dedent
--> 206 from matplotlib import mpl # pulls in most modules
     208 from matplotlib.dates import date2num, num2date,\

/usr/local/lib/python2.6/dist-packages/matplotlib/mpl.py in <module>()
----> 1
       3 from matplotlib import artist
       4 from matplotlib import axis
       5 from matplotlib import axes
       6 from matplotlib import cbook
       7 from matplotlib import collections

/usr/local/lib/python2.6/dist-packages/matplotlib/artist.py in <module>()
       4 import matplotlib.cbook as cbook
       5 from matplotlib import docstring
----> 6 from transforms import Bbox, IdentityTransform, TransformedBbox, TransformedPath
       7 from path import Path

/usr/local/lib/python2.6/dist-packages/matplotlib/transforms.py in <module>()
      32 import numpy as np
      33 from numpy import ma
---> 34 from matplotlib._path import affine_transform
      35 from numpy.linalg import inv

ImportError: /usr/local/lib/python2.6/dist-packages/matplotlib/_path.so: undefined symbol: PyArray_API

I may have a problem with the svn update but I'm not quite sure.
Maybe it is just a temporary compatibility problem in between matplotlib and numpy.

Can someone comment on that?

I'm using:
numpy At revision 7773.
scipy At revision 6120.
matplotlib At revision 7985.
