Comment 5 for bug 464434

Then, based on #4, what is it to be done?
 1. Make kubuntu-dev-tools depend, as if you are developer in kubuntu you need the ubuntu-dev-tools also
 2. Make kubuntu-dev-tools suggest, so you will get a warning (but I find it weaker than 1, considering that u-d-t is not desktop related)

My vote goes for 1 without blinking.
