I think you should do "sudo apt-get install python-dev"

thanks, this didn't seem to work. I get a whole range of errors, most
importantly

SystemError: Cannot compiler 'Python.h'. Perhaps you need to install
python-dev|python-devel.

Apparently, according to numpy installation guide
(here)
i got the wrong compiler installed. How do I find out which 1 I got?

Ubuntu actually does this by default (i.e. the default prefix expands to 
/usr/local on ubuntu and debian).

But I think we should tell people to use the --user for python 2.6 and 
above by default: that's the safest method, does not require sudo and 
works on every platform,

cheers,

Preferably,

sudo python setup.py install --prefix=/usr/local

and then you don't mess up your package manager.

[Ian Goodfellow]

To do a standard installation, run
sudo python setup.py install
from inside the numpy directory

Then your import should work elsewhere.

By the way, "import *" can cause difficulties when you're working with
several different files. For example, if you have a function called 'save'
somewhere that imports something that does 'from numpy import *' you'll have
problems because there is a numpy.save. It's better to import numpy with a
shorter name, ie, "import numpy as N" or "import numpy as npy" than to drop
the namespace altogether.

Did you consider installing the Ubuntu provided packages, e.g. via apt-get
or the Synaptic Package manager? That is *much* easier - but you
won't get the very latest versions.

> Having unpacked numpy and running the standard commnad in idle

Could you clarify what you did? You don't just unpack the archive and use
it as it - there is C code that must be compiled etc.
