Comment 2 for bug 370176

I was trying to reproduce this bug to confirm it since I get the same error with other packages (not with python-visual) but can't get python visual to work this package dependencies seem not handled properly:

it required numarray (wasn't installed) or numeric (was installed):
>>> from visual import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/visual/__init__.py", line 15, in <module>
    import array_backend
  File "/usr/lib/python2.6/dist-packages/visual/array_backend.py", line 50, in <module>
    raise RuntimeError, "Neither Numeric nor numarray could be found."
RuntimeError: Neither Numeric nor numarray could be found.

Then after having installed numarray:
>>> from visual import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/visual/__init__.py", line 24, in <module>
    import crayola
ImportError: No module named crayola

I cannot find crayola in my packages...
