Python can't find setuptools
<p>I got the following ImportError as i tried to setup.py install a package:</p>

<pre><code>Traceback (most recent call last):
   File "setup.py", line 4, in &lt;module&gt;
    from setuptools import setup, Extension
ImportError: No module named setuptools
</code></pre>

<p>This happens although setuptools is already installed:</p>

<pre><code>amir@amir-debian:~$ sudo apt-get install python-setuptools
[sudo] password for amir: 
Reading package lists... Done

python-setuptools is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
</code></pre>

<p>Why can't python find the setuptools module? </p>
