It seems like you are reading the message correctly, but you are 
focusing on the wrong part. The problem here is gail, not gtk+. What 
should happen is gail-1000 is installed as part of this upgrade, and 
then the block is resolved. The output of "equery list -p gail" should 
tell you if gail-1000 is masked for some reason. Unmasking gail-1000 
should resolve the block, but why it is masked in the first place is 
rather a mystery.
