Hi,
I'm not used to seeing all the additional messages below the
blockage indication. Can someone possibly help me understand how to
read this?

Are there really application packages that cannot be installed at
the same or is only about qt and possibly the USE flags I've got?

I tried removing qjackctl (the only world package I spotted in the
list) but that didn't help.

What to try next?

Thanks,
Mark
