Hello and thanks for maintaining this package in Debian!
I noticed that the debian/copyright states:
[...] | Parts of this software are derived from DXPC project. These copyright | notices apply to original DXPC code: | | Redistribution and use in source and binary forms are permitted provided | that the above copyright notice and this paragraph are duplicated in all | such forms. | | THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY EXPRESS OR IMPLIED | WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF | MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE. | | Copyright (c) 1995,1996 Brian Pane | Copyright (c) 1996,1997 Zachary Vonler and Brian Pane | Copyright (c) 1999 Kevin Vigor and Brian Pane | Copyright (c) 2000,2001 Gian Filippo Pinzari and Brian Pane [...]
This license lacks the permission to modify the DXPC code. Hence, the original DXPC code does not appear to comply with the DFSG. And the nx-libs-lite is in part derived from DXPC code.
This basically means that nx-libs-lite includes parts which are non-free (as they are derived from non-modifiable code) and are also possibly legally undistributable (as they are non-modifiable, but actually modified). The combination with the rest of nx-libs-lite (which is GPL-licensed) may also be legally undistributable (since the license with no permission to modify is GPL-incompatible).
If there's anything I misunderstood, please clarify.
Otherwise, please address this issue as soon as possible. The copyright owners for the original DXPC code should be contacted and persuaded to re-license under GPL-compatible terms.
Thanks for your time. Bye.
I/we will investigate this asap. Thanks for bringing this up.
Greets, Mike
