Hello,
There should be two files for the license, one for the GPL and one for the additional permissions of the Lesser/Library GPL.
I do see two files in the source tree :
COPYING
COPYING.LIB
The GPL 3 file
The Library GPL file linked to version 2 of the GPL or later (maybe it should be updated to be the Lesser GPL file).
(Library GPL was renamed Lesser GPL at some point in time because it could apply to something else than a library,
in both cases it is LGPL.)
It seems OK to me. In this file, I have
GNU LIBRARY GENERAL PUBLIC LICENSE
2 Version 2, June 1991
3
4 Copyright (C) 1991 Free Software Foundation, Inc.
5 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.
8
9 [This is the first released version of the library GPL. It is
10 numbered 2 because it goes with version 2 of the ordinary GPL.]
Do you have anything different in your .tar.gz ? Or did you get confused between COPYING and COPYING.LIB ?
Best regards,
Laurent Lyaudet
