[Numpy-discussion] Test failures - which dependencies am I missing?

Hi,

When I build NumPy and then run the tests on Ubuntu (10.04 LTS) and Debian 
(6.1), I always seem to get several failures. I guess most of these failures 
come from not having some dependencies installed, but I can't figure out which 
ones by reading e.g. http://docs.scipy.org/doc/numpy/user/install.html. It 
would be great if someone could tell me what I've likely missed!

I remember Gael Varoquaux posted a few weeks back with some of the same errors 
(http://thread.gmane.org/gmane.comp.python.numeric.general/49032/). He was also 
using Ubuntu (though a newer version).

Anyway, on Ubuntu here are the errors - other than known failures - after 
"python setup.py build_ext -i" (or python setup.py build_ext -i --
fcompiler=gnu") followed by nosetests:

I see something similar on Debian 6 (x86_64). You can see the full output for 
that at https://jenkins.shiningpanda.com/scipy/job/NumPy/
PLATFORM=debian6,PYTHON=CPython-2.7/19/consoleFull, in case it helps.


Thanks,
Chris
