As of July 20th, 2009, Portage only has Kile version 2.0.3-r1, which is only compatible to KDE 3.5. There is a newer version as of today, 2.1 beta 1, which is compatible to KDE 4.x. I'm wondering if the maintainer can add this version into Portage. Reproducible: Always
It is already in kde-testing overlay, we are waiting for stable release.
2009-08-23 Kile 2.1 beta 2 release please bump... :-)
Done :]
And it's in Portage...
