Although I've found this: http://bugs.gentoo.org/show_bug.cgi?id=15163 whici implies that an ebuild already exists, I can't find it, and can't verify if this latest version really needs db2, as they only advise to use it on their website.
Created attachment 8961 [details] ebuild for kbabel
From kbabel homepage: "KBabel is included in package kdesdk of KDE (1.0 is a part of KDE 3.1)." so having a seperate KBabel ebuild makes no sense to me. If there are no objections I'll mark as wontfix.
Okydokey! :-)
ok, kbabel is part of kdesdk.
