title: OSX Python3.6: Installing and linking GDAL
body: <p>I am having issues linking gdal with Python3. </p>
  
  <p>I have successfully installed gdal using homebrew, where I get the following responses in terminal:</p>
  
  <pre><code>$ gdal-config --version
  2.1.3
  $ ogr2ogr --version
  GDAL 2.1.3, released 2017/20/01
  </code></pre>
  
  <p>However in Python3, on trying to import osgeo (or gdal) I am getting:</p>
  
  <pre><code> ModuleNotFoundError: No module named 'osgeo'
  </code></pre>
  
  <p>I have tried installing gdal using pip3, however the following error is returned:</p>
  
  <pre><code>error: command 'clang' failed with exit status 1 
  </code></pre>
  
  <p>Any ideas on how to sort this out? </p>
  
  <p>Thanks!</p>
