  Error: gdal-config not found
  The gdal-config script distributed with GDAL could not be found.
  If you have not installed the GDAL libraries, you can
  download the source from  http://www.gdal.org/
  If you have installed the GDAL libraries, then make sure that
  gdal-config is in your path. Try typing gdal-config at a
  shell prompt and see if it runs. If not, use:
   --configure-args='--with-gdal-config=/usr/local/bin/gdal-config'
  with appropriate values for your installation.
