The very first error is "#error "SysV or X/Open-compatible Curses header file required"", which is at very least odd, as the dep is listed in the ebuild, but for some reason not detected by configure. Attach config.log.
> checking for C++11 support... no This failure is a bit odd too - IIRC, gcc 4.9 should be OK. Also, why are your C{XX}FLAGS empty ?
My CFLAGS are empty because I tested and found this error to not be due to my CFLAGS so I can report the bug with no CFLAGS and make your life a little easier.
Are you still able to reproduce this problem on 0.9.6?
