title: Why cv2.so missing after opencv installed?
body: <p>Today I installed opencv 2.4.4 to Ubuntu 12.10</p>
  
  <p>But import cv2 not works.</p>
  
  <pre><code>root@-:~# python
  Python 2.7.3 (default, Sep 26 2012, 21:53:58) 
  [GCC 4.7.2] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import cv2
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named cv2
  &gt;&gt;&gt; 
  </code></pre>
  
  <p>As I understand cv2.so missed, so python don't see where opencv</p>
  
  <pre><code>root@-:~# find / -name "cv.py"
  /root/opencv-2.4.4/modules/python/src2/cv.py
  root@-:~# find / -name "cv2.so"
  root@-:~#
  </code></pre>
  
  <p>My setup steps look like</p>
  
  <pre><code>wget http://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.4/OpenCV-2.4.4a.tar.bz2
  tar -xjf OpenCV-2.4.4a.tar.bz2
  cd opencv-2.4.4
  mkdir release
  cd release 
  cmake -D CMAKE_BUILD_TYPE=RELEASE   -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..
  make &amp;&amp; make install
  echo "/usr/local/lib" &gt;&gt; /etc/ld.so.conf.d/opencv.conf
  ldconfig  
  echo "PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig" &gt;&gt; /etc/bash.bashrc
  echo "export PKG_CONFIG_PATH" &gt;&gt; /etc/bash.bashrc
  </code></pre>
  
  <p>Where is cv2.so ? And why it was missed ?</p>
