The latest version of k3b in portage is 2.0.2, with some patches to make it compile. I've recently been searching for a way to set a project's volume name by command line, cf. http://forum.kde.org/viewtopic.php?f=153&t=119772 It seems that version 2.0.2 is not the latest release. It's a bit confusing, as both http://k3b.org/ and http://k3b.kde.org/ say so, but other distributions seem to have k3b 2.0.80. I checked out git://anongit.kde.org/k3b which seems to be the current state of the k3b code, something like svn trunk (sorry, I'm not familiar with git) and could build the code without any patches on my amd64 stable machine. The resulting k3b binary worked flawlessly and – speaking of the above research I did – has a complete DBUS interface including /projects/, which is actually lacking in 2.0.2. At the moment, I don't know where to get an official 2.0.80 tarball, but probably you know?! It would be fine if Gentoo would not fall behind other distributions here.
I suspect their 2.0.80 is something they packaged themselves; I see no evidence of a 2.0.80 tag. There is a k3b live ebuild available in the KDE overlay. As for a snapshot, I'll think about it.
I agree with doing a snapshot, the 2.0.2 tag is over three years old and there have been quite some commits since then.
Snapshot added to portage, thanks for the report.
Reopening as that snapshot lacks all locales.
I put a comment in the ebuild about that; basically, git doesn't have the locales, and I don't know if I'm able to generate them. If anyone has ideas on that, I'm all ears.
for info only: With this snapshot k3b shows 2.0.80 in "about".
