[igraph] How install Python-IGraph 0.5.2 into Ubuntu 9.04

[Domenico Conti]

Hi, I'm Dominico, I'm trying to install igraph python-0.5.2 in Ubuntu 
9.04. I saved the folder igraph-python-0.5.2 on the desktop. From the 
terminal I move in this folder and I type the command:

python setup.py build

But earning a large number of errors like those below:

Include path: /usr/include /usr/local/include
Library path:
/usr/lib/python2.6/distutils/dist.py:266: UserWarning: Unknown

(continue in this way)

What can I do? I need help because I need to do work for my thesis.
