You got no other output? Portage then quit quickly, decided to d nothing 
and then gave you the below?

                            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I missed this earlier. That is new, I have no idea what it means

with ncurses above, portage says it needs ncurses version >5.2-r2 with 
subslot 0/5 and unicode set in USE. It doesn't say WHY it needs it, only 
that it does, but something in your system configs prevents it.

Start with:
grep -r unicode /etc/portage
grep -r ncurses /etc/portage

That tends to show quickly why you have a USE unset or if ncurses is 
blocked somehow
