The various output .zips available for spell-norwegian, e.g. https://alioth.debian.org/frs/download.php/2357/no_NO-pack2-2.0.10.zip make mention in their README files of the GPL like this....
"License: GNU General Public license"
which could refer to any version, while the source package spell-norwegian-2.0.10 has a COPYING for the GPLv2 and the website explicitly says "GPLv2 or later".
Should those READMES be updated to mention "GPLv2 or later", and even better, have those .zips include a copy of a GPLv2 COPYING file.
