This problem can be eliminated by adding the following line to mdport.c:

#define NCURSES_INTERNALS

I will attach a patch.

So upon seeing the 30 days removal notice for rogue stating that it doesn't compile against ncurses 6 (referencing this bug for that complaint), I feel I have to point out that it does:

$ ldd $(which rogue)
        linux-vdso.so.1 (0x00007ffc6f5e3000)
        libncurses.so.6 => /lib64/libncurses.so.6 (0x00007f394d27a000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f394d0ae000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f394d777000)

And runs just fine when I boot it up. Specifically I have =sys-libs/ncurses-6.1-r3 , with the "cxx" and "unicode" useflags enabled (and none of the others, except for ABI_X86 stuff), and no patches for rogue anywhere on my system. I also don't have any user patches for ncurses. So the problem is either with something more specific than just it being major version 6 of ncurses (e.g. some useflag I don't have enabled causing problems when it is), or has been fixed by a new version of the ncurses ebuild since the report was filed.
