Ok.. I have now tried to use the lib directly from ruby.
It still outputs garbage.   I am unsure if im using the right calls
for outputting ?


require 'dl/import'
module Curses
extend DL::Importable
dlload "libcurses.so"
typealias "WINDOW", "void*"
typealias "attr_t", "unsigned long"
extern "WINDOW initscr()"
extern "int endwin()"
extern "int getch()"
extern "int cbreak()"
extern "int noecho()"
extern "int refresh()"
extern "int addstr(const char *)"
end
Curses.initscr
Curses.cbreak
Curses.noecho
s = [0x250c, 0x2510, 10, 0x2514, 0x2518].pack("U*")+0.chr
Curses.addstr(s)
Curses.refresh
Curses.getch
Curses.endwin


Im now trying to install ncurses-5.4 to see if it makes a difference.
btw: Thomas E. Dickey you amaze me everytime you find xterm/ncurses
related stuff in different newsgroups.. how do you do?
