Seems like kdevelop can use some updating, last update was in october, since then there have been 2 new binary snapshots fixing quite a few bugs. If possible getting the update as of 2007-December-04 into portage would be useful.
Right, binary releases. Neither do they provide source tarballs, nor do they tag the snapshots or mention the svn revision anywhere. I'm aware that KDevelop is - unfortunately - a very moving target, but since no sufficient upstream information is available and I do not know, if there is even one who wants to keep up with these snapshots and the corresponding bugs floating in.
Feel free to reopen the bug, when the upstream developers choose to provide the nevessary information.
