    #{self.name.sub(/^KlassPrefix/,'').gsub(/([a-zA-Z\d])([A-Z])/,'\1-\2').gsub(/([a-zA-Z\d])([A-Z])/,'\1-\2').downcase} requires the GDAL framework and Matplotlib to be installed first,
    otherwise the installation will fail. In case of problems, try installing
    them:

      brew cask install gdal-framework matplotlib

    and then reinstall QGIS

      brew cask uninstall qgis && brew cask install qgis
