Hi again,

I am trying to install and use the bvp package in scipy. I download
the source file in my home directory, then

  $ cd bvp-0.2.4
  $ sudo python setup.py build
  $ sudo python setup.py install

When I type (in python)
>>> import scipy.special
>>> import bvp

Iget the following error message:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "bvp/__init__.py", line 6, in <module>
   import colnew
 File "bvp/colnew.py", line 63, in <module>
   import _colnew
ImportError: No module named _colnew

I use ubuntu 8.10 on a Dell inspiron. Thank you very much
(especially Robert Kern for rapid answer),

That's how to build it. Now, you need to install it.

 $ sudo python setup.py install

Note that this, and the previous command, should be done at a terminal
shell, not the Python prompt.

Don't use pkgload(). Just import scipy.special.
