title: Importing psutil causes ImportError
body: <p>I'm trying to get <code>psutil</code> to work on our server. It is running AIX. There is no <code>pip</code>. So, I downloaded the <a href="https://github.com/Infinidat/psutil/tree/aix" rel="nofollow noreferrer">repo from github</a>(AIX build of psutil), <code>cd</code> into it, and ran Python CLI.</p>
  
  <p>Now, trying to do <code>import psutil</code> causes an ImportError.</p>
  
  <pre><code>bash-4.2$ python
  Python 2.7.5 (default, Aug 16 2013, 14:02:06) [C] on aix6
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import psutil
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "psutil/__init__.py", line 163, in &lt;module&gt;
      from . import _psaix as _psplatform
    File "psutil/_psaix.py", line 20, in &lt;module&gt;
      from . import _psutil_aix as cext
  ImportError: cannot import name _psutil_aix
  &gt;&gt;&gt; import psutil              ## IMPORTING AGAIN THE SAME SESSION CAUSES DIFFERENT ERROR
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "psutil\__init__.py", line 39, in &lt;module&gt;
      from . import _common
  ImportError: cannot import name _common
  </code></pre>
  
  <p>What can I do here? Installing the module locally using <code>python setup.py install --user</code> is also not working:</p>
  
  <pre><code>bash-4.2$ python setup.py install --user
  running install
  running build
  running build_py
  running build_ext
  building 'psutil._psutil_aix' extension
  xlc_r -ma -I/opt/freeware/include -DAIX_GENUINE_CPLUSCPLUS -Wl,-brtl -g -DNDEBUG -O2 -DPSUTIL_POSIX=1 -DPSUTIL_VERSION=532 -DPSUTIL_AIX=1 -I/opt/freeware/include/python2.7 -c psutil/_psutil_common.c -o build/temp.aix-7.1-2.7/psutil/_psutil_common.o
  unable to execute xlc_r: No such file or directory
  error: command 'xlc_r' failed with exit status 1
  </code></pre>
  
  <p>I've tried doing the same with the <code>tweepy</code> package which runs perfectly(given <code>six</code>, <code>requests</code>, and <code>requests_oauthlib</code> are already installed).</p>
  
  <p>EDIT: Just to make clear this is not limited to AIX, I've tried doing the same on Windows, and it gives the same error.</p>
