Confirmed the new MASTER_SITE works for me.
I agree with this new value for MASTER_SITES. Within the print/hplip file ${WRKSRC}/installer/pluginhandler.py, the download location for the plugin is revealed: The function __getPluginInformation downloads information about the available plugins from http://hplip.sf.net/plugin.conf. This file clearly shows the official URL for downloading the plugin is: http://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/hplip-%%PORTVERSION%%-plugin.run

The URL change reflects a recent website change by HP, and was preventing print/hplip-plugin from fetching correctly. The LICENSE change reflects the fact that the introductory license to the python source files mention that a later version of the GPL can optionally be used.
