That solved the problem, thanks! I now have 4 remaining test failures
of the form:

======================================================================
ERROR: Test for new slice functionality (EJS)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/scipy/sparse/tests/test_sparse.py",

    return asmatrix(self.toarray())
  File "/usr/lib/python2.4/site-packages/scipy/sparse/sparse.py", line

line 380, in csrtodense
    return _sparsetools.csrtodense(*args)

Any ideas?

Cheers,

Tim
