Calibre bundles non-free unrar code. The license of unrar code is incompatible with the GPL license (ebuild states that the whole program is licensed under the GPL-2 which is actually wrong. LICENSE file states that the code is distributed under GPLv3). src/unrar/license.txt for more details
> src/unrar/license.txt for more details This we already have as "unRAR" license. In addition, there are several other licenses, most of them listed in the COPYRIGHT file: GPL-3+ GPL-3 GPL-2+ GPL-2 GPL-1+ LGPL-3+ LGPL-2.1+ LGPL-2.1 BSD MIT Old-MIT Apache-2.0 public-domain || ( Artistic GPL-1+ ) CC-BY-3.0 OFL-1.1 PSF-2 This isn't a complete list, though. For example, directory resources/fonts/prs500/ seems to contain some proprietary fonts from Bitstream Inc.
(In reply to comment #1) The ebuilds are fixed in cvs to include all of those licenses LICENSE, and the prs500 fonts are removed.

Okay, RESTRICT=mirror is set in all ebuilds.
I guess it would be best if the font issue was sorted out upstream. The three fonts are: tt0003m_.ttf: Swiss 721 (i.e. the Bitstream variant of Helvetica) tt0011m_.ttf: Dutch 801 Roman (Bitstream variant of Times Roman) tt0419m_.ttf: Courier 10 I wonder why these are needed anyway, since the package includes the Liberation fonts already.
Well, google search for calibre+prs500+fonts already turns up at least 2 bugs involving distro complaints about these fonts: http://oldbugs.calibre-ebook.com/ticket/1517 http://oldbugs.calibre-ebook.com/ticket/3832 So, it seems as though upstream couldn't care less.
The prs500 fonts are no longer bundled in calibre-1.5.
This old bug on Launchpad may be relevant: https://bugs.launchpad.net/calibre/+bug/1363536
