have you tried a recent numpy/scipy svn, i.e.:
  svn co http://svn.scipy.org/svn/numpy/trunk numpy
  svn co http://svn.scipy.org/svn/scipy/trunk scipy
(see also http://new.scipy.org/Wiki for more information
- under-development)
Concerning the naming: scipy core etc.: have a look
at  http://numeric.scipy.org/
which explains this.
To summarize: it is really numpy+scipy what you want. ;-)

It would be great if you could post the
details of your problems.
I am sure that these can be solved!
(Actually, with the most recent numpy/scipy it should
work fine...)

This is a statistical test, so it may fail from time to time.
If you rerun `scipy.test(10)` usually this test will pass.
It has been discussed on scipy-dev to run statistical
tests a couple of times and only if it fails all
the time to raise an error (not yet implemented).

Best, Arnd
