LICENSE="GPL-2" The licensing is very sloppy: In README: License ------- As the name might suggest, this software is distributed under the terms of the GNU Public License, version 2. Please find a copy of the GNU Public License included with the source archive in the file COPYING, it will also be accessible from the server itself; read the startup banner for details. But in the startup banner, any version of the GPL is noted: GNUMP3d is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions. Every file with a GPLv2 header notes GPLv2-or-later. There are also a few files which lack a license, so GPLv2-only may be the license on those. A lot of files mention that they're under the Perl license, or something similar to: This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. As a result, as far as I can tell, LICENSE should be: LICENSE="GPL-2 GPL-2+ || ( Artistic GPL-1+ )"
In correction, as far as I can tell, LICENSE should be: LICENSE="GPL-2+ || ( Artistic GPL-1+ )" Here it is noted that the license is GPLv2-or-later (with the project admin being the primary author): https://savannah.gnu.org/projects/gnump3d
