title: when installing pyaudio, pip cannot find portaudio.h in /usr/local/include
body: <p>I'm using mac osx 10.10
  As the PyAudio Homepage said, I install the PyAudio using</p>
  
  <pre><code>brew install portaudio 
  pip install pyaudio
  </code></pre>
  
  <p>the installation of portaudio seems successful, I can find headers and libs in /usr/local/include and /usr/local/lib
  but when I try to install pyaudio, it gives me an error that</p>
  
  <pre><code>src/_portaudiomodule.c:29:10: fatal error: 'portaudio.h' file not found
  #include "portaudio.h"
           ^
  1 error generated.
  error: command 'cc' failed with exit status 1
  </code></pre>
  
  <p>actually it is in /usr/local/include
  why can't it find the file?
  some answers to similar questions are not working for me(like using virtualenv, or compile it manually), and I want to find a simple way to solve this.</p>
