It's not k3b.

The blocker output at the end basically says "qt-4.7.1 is being pulled in to 
satisfy a depends on >=qt-4.6.3 pulled in by k3b"

It's not only k3b pulling in qt *greater than or equal to" 4.6.3, many 
packages will do that. k3b just happened to be the first one portage found.

There you go. That's the one.

Everything else in the conflicts list is in the format of "qt-4.7.1 pulled by 
>=qt-4.6.3 pulled in by..."

That one starts with 4.6.3, it's different. The pulled in by simply says that 
it's the version chosen by portage because k3b (and lots of other stuff, 
remember) needs it. Which doesn't explain why it's *that* version.

Till you look at eix qt-multimedia and see that 4.6.3 is keyword arch.

I bet you forgot to keyword it unstable.

Your brain? You tried to start KDE without qt! That's like wondering why the 
box won't boot without a kernel :-)

You *sure* the gubment isn't putting something in the drinking water down 
South where you are?

well, at least you relieved the evening tedium of watching config updates from 
a server in Nigeria scroll on down the window :-)
