[SciPy-User] Can not import sigtools (latest svn, python 3.1)

[Nadav Horesh]

>>> from scipy.signal import sepfir2d
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    from scipy.signal import sepfir2d
  File "/usr/lib64/python3.1/site-packages/scipy/signal/__init__.py", line 11, in <module>
    from .fir_filter_design import *
  File "/usr/lib64/python3.1/site-packages/scipy/signal/fir_filter_design.py", line 6, in <module>
    import sigtools

I edited "fir_filter_design.py" and chaned to:

from scipy.signal import sigtools

but then I got the error:

  File "/usr/lib64/python3.1/site-packages/scipy/signal/__init__.py", line 7, in <module>
    from . import sigtools
ImportError: cannot import name sigtools

I do not know how to fix this. Any ideas?
