I did what you said, but when reinstalling scipy I got this error:

  File "Lib/sandbox/setup.py", line 22, in configuration
    config.add_subpackage(p)
  File 
"/usr/local/lib/python2.4/site-packages/numpy/distutils/misc_util.py", line 
765, in add_subpackage
    caller_level = 2)
  File 
"/usr/local/lib/python2.4/site-packages/numpy/distutils/misc_util.py", line 
741, in get_subpackage
    caller_level = caller_level+1)
  File 
"/usr/local/lib/python2.4/site-packages/numpy/distutils/misc_util.py", line 
541, in __init__
    raise ValueError("%r is not a directory" % (package_path,))
ValueError: 'Lib/sandbox/odr' is not a directory
