I am trying to install ncurses for ruby on windows. I have not installed ncurses before on my machine. I thought that having the "ruby devkit", it had asked for would be enough, but now I am being asked to specify options... I don't know which options to pick, or if I need to do/install other things for the gem to get installed:
C:\Ruby193\Devkit>gem install ncurses -- --ruby=C:/Ruby193/bin/ruby --without-make-prog --without-opt-dir
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing ncurses:

WHAT A PAIN, I just want to get this gem installed so I can run this:
require 'curses'
cols = Curses.stdscr.maxx
msg = "random_string"
str = msg.center(msg.length + cols - msg.length - 5 - 3)
puts "<!-- #{str}-->"
