It seems that the libncurses failure is caused by missing terminfo.

NAME
terminfo - terminal capability data base
SYNOPSIS
/usr/lib/terminfo/*/*
DESCRIPTION
Terminfo is a data base describing terminals, used by
screen-oriented programs such as vi(1), rogue(1) and
ncurses(3). Terminfo describes terminals by giving a set
of capabilities which they have, by specifying how to per-
form screen operations, and by specifying padding require-
ments and initialization sequences.

>How-To-Repeat:
# ls -l /usr/lib/terminfo/
ls: /usr/lib/terminfo/: Not a directory
>Fix:
need to locate the terminfo which is useful for vi and libncurses
