title: Pyaudio 2.11 Installation Fail
body: <p>If I try installing PyAudio 2.11 using</p>
  
  <pre><code>python setup.py install
  </code></pre>
  
  <p>I get an error (only copied the error section, not the entire output):</p>
  
  <pre><code>src/_portaudiomodule.c(29) : fatal error C1083: Cannot open include file: 'portaudio.h': No such file or directory
  error: command 
  'C:\\Users\\lukec\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\Bin\\cl.exe' failed with exit status 2
  </code></pre>
  
  <p>BUT - if I use pip install pyaudio, it works fine. Why the discrepancy?</p>
