Probably the same as #669096. You'd need to modify it to look for tinfow before tinfo.
I postponed it again, I'm moving in my new place next month, I intend to catch up on everything I said I'd do after that.
Also if it becomes more urgent for anyone, dont hesitate to tell it to me here.
This bug affects me, because ncurses[tinfo] is needed for youcompleteme, see:

I made this patch, that solves the issue for me.
I'm installed but haven't reconfigured everything yet, I'll take a look and test your patch on 08/19, thank you for your contribution ;)
Thanks for the patch, works here too.
Confirmed it works.
I havent taken time to talk to upstream/include patch in repo. I'll try contacting upstream first as dropping the patch in /etc/portage/patches is enough atm.
