I am using Numeric versions 20.2.1 and 20.3 (for Python 2.1 and 2.2,

  File "scipy_base/utility.py", line 30, in ?
    cast = {Numeric.Character: toChar,
AttributeError: 'Numeric' module has no attribute 'Character'

Travis, you mentioned earlier that such error can only occure if one has
"unusual" Numeric installed. I checked from NumPy CVS and verified that
attribute 'Character' was introduced first time to Numeric version

So, shall we agree that SciPy requires NumPy version 21.x? 

It has a short term drawback because those who use NumPy from their
OS distribution, cannot use SciPy for awhile. For example, latest NumPy in
debian woody is 20.3.


PS: In order to build the latest SciPy from CVS, one needs to create a
