title: Adding Python package to Buildroot
body: <p>I am running an embedded system on Buildroot. I want to run a Python application on it which requires the PyDrive module.</p>
  
  <p>I am getting a PYTHONPATH error which looks like:</p>
  
  <pre><code>TEST FAILED: /home/desousa/buildroot/build/target/usr/lib/python2.7/site-packages/ does NOT support .pth files
  error: bad install directory or PYTHONPATH
  
  You are attempting to install a package to a directory that is not
  on PYTHONPATH and which Python does not read ".pth" files from.  The
  installation directory you specified (via --install-dir, --prefix, or
  the distutils default setting) was:
  
      /home/desousa/buildroot/build/target/usr/lib/python2.7/site-packages/
  
  and your PYTHONPATH environment variable currently contains:
  
      '/home/desousa/buildroot/build/target/usr/lib/python2.7/sysconfigdata/'
