title: scikits audiolab installation error
body: <p>I am using mint Linux Mint 13 maya (linux  3.2.0-23-generic x86-64)<br>
  I am trying to install scikits.audiolab for performing some audio signal processing. I have downloaded all prerequisites i.e. (python-dev python-numpy python-setuptools libsndfile-dev). 
  I have made site.cfg as</p>
  
  <pre><code>[sndfile]
  include_dirs = /usr/include/
  library_dirs = /usr/lib/x86_64-linux-gnu/
  </code></pre>
  
  <p>I get following error  </p>
  
  <pre><code>SndfileInfo:
      FOUND:
  libraries = ['sndfile']
  library_dirs = ['/usr/lib/x86_64-linux-gnu/']
  include_dirs = ['/usr/include/']

  <p>How do I make the setup.py find the libraries. Is there something I am missing ?
  I have seen <a href="http://forum.ubuntu-fr.org/viewtopic.php?pid=3748397" rel="nofollow noreferrer">http://forum.ubuntu-fr.org/viewtopic.php?pid=3748397</a> and <a href="https://stackoverflow.com/questions/8461055/scikits-audiolab-on-ubuntu-oneiric-importerror-no-module-named-sndfile">scikits.audiolab on Ubuntu Oneiric - ImportError: No module named _sndfile</a></p>
  
  <p>This is causing so much frustation</p>
  
  <p>UPDATE</p>
  
  <p>In one of my PC's this error was removed on completely un-installing the scikits-audiolab and alsa and then updating the apt-get before re-installing alsa and scikits-audiolab.</p>
