[Visualpython-users] Python 2.7.1 and VPython 5.4 on OS X 10.5.8 broken?

I'm trying hard to update my classroom MacBooks running 10.5.8 to Python 2.7
and VPython 5.4. However, upon running

from visual import *
sphere()

from VIDLE I get this:

ImportError: numpy.core.multiarray failed to import

Traceback (most recent call last):
  File "Untitled", line 1
    from visual import *

"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/visual/__init__.py",

  File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ttfquery/glyph.py",

    import Numeric
ImportError: No module named Numeric

I've looked through the docs; I'm lost. Anyone else seeing this behavior?
