Very strange.  I can't reproduce it here (on gutsy, but running
ipython from my own tree). What's odd is this:

In [1]: import Numeric

In [2]: print Numeric.ArrayType
<type 'array'>


So Numeric *most definitely* has an ArrayType member. Try doing the
same as I did, also showing us whether you started ipython with -pylab
or not.  There may be something odd about your Numeric installation.
Also do this:

In [3]: Numeric?
Type:           module
Base Class:     <type 'module'>
Namespace:      Interactive
File:           /usr/lib/python2.5/site-packages/Numeric/Numeric.py

[etc]

It's possible that you have in your path a file called Numeric.py
which is not the 'real' Numeric module.  This would explain your
problem and why nobody else sees it.
