the current k3b version in portage wont compile with kde 4 libs. A version bump would fix this. Reproducible: Always Steps to Reproduce: emerge k3d (with kde 4.x) Actual Results: kde 3.5 required
When there is version better than alpha yes, now it is not usable, if you want to test it you can find it in kde-testing overlay.

We added such version to main tree while back.
However, Why don't you want rename 'sabj' (for KDE-4) and make separate package? It is logically should be 'k4b', I think. (I am seriously)
The package is still the same - the supported KDE version is what's changing in the newer versions.
