Based on my reading, the libfcgi-perl debian package has a licensing
issue. The base package includes a file LICENSE.TERMS, which shows a
license roughly equivalent to the MIT license. It does however
include the following phrase:
The following terms apply to all files associated with the Software
and Documentation
unless explicitly disclaimed in individual files.
There are three files, fcgios.h, os_unix.c, and os_win32.c, which
include a header that conflicts with the base MIT-style terms. They
include the following:
* Copyright (c) 1995 Open Market, Inc.
* All rights reserved.
*
* This file contains proprietary and confidential information and
* remains the unpublished property of Open Market, Inc. Use,
* disclosure, or reproduction is prohibited except as permitted by
* express written license agreement with Open Market, Inc.
*
* Bill Snapper
* snapper@openmarket.com
This would appear to me to be "explicitly disclaimed" as not following
the LICENSE.TERMS license. And also certainly not following the DFSG.
While I believe this conflict was an error in the initial release of
this code (nearly 20 years ago), I also don't see how this could be
resolved without an explicit relicensing by Open Market. This may
also impact other fcgi packages in Debian.
