[SciPy-user] problem with weave tutorial

[Gary Robinson]

I installed scipy yesterday.

  from scipy import weave
  weave.test()

runs fine.

But when I try to run examples in the weave tutorial (http://projects.scipy.org/scipy/scipy/browser/trunk/scipy/weave/doc/tutorial.txt), I get errors. For instance, the tutorial has the following:

        >>> a = 1
        >>> a = weave.inline("return_val = Py::new_reference_to(Py::Int(a+1));",['a'])
        >>> a
        2

But when I try to run it, I get the following error. Can anyone tell me why? This is on OS X 10.5.2.
