Hi Nils,

it looks like you have numpy.testing too, so the fix might be ok.

The error you see comes from test_umfpack.py not being updated to new 
testing framework. So what is the current way of importing Tester? 
numpy.testing works for me.

my installation behaves in the following way:

# original:
In [7]: from scipy.testing.pkgtester import Tester
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

/home/eldaran/<ipython console>

ImportError: No module named testing.pkgtester

# new:
In [8]: from numpy.testing import Tester

In [9]: import numpy
In [10]: numpy.__version__
Out[10]: '1.2.0.dev5615'
In [11]: import scipy
In [12]: scipy.__version__
Out[12]: '0.7.0.dev4603'


Related question: what versions of scipy/numpy should be scikits 
compatible with? I will try to update umfpack to work both with the last 
release and the svn.
