Hi William,

Sorry I didn't get back to you sooner.  I finally got back around to playing
with this again.  Here are the answers to your questions:

>gem list --local | grep curse
ncurses (0.9.1)

The test script prints:
true

The ncurses examples all seem to work and display color.  I did have to edit
them to add require 'rubygems' at the top.

I also tried playing with the sup code a bit.  If I comment out lines 133-4
in lib/sup/colormap.rb:

#      Curses.init_pair id, fg, bg or raise ArgumentError,
#       "couldn't initialize curses color pair #{fg}, #{bg} (key #{id})"

sup loads, but everything is in black and white and a bit difficult to
read.  I also tried uncommenting that, then changing Curses to Ncurses so it
looks like this:

      Nurses.init_pair id, fg, bg or raise ArgumentError,
       "couldn't initialize curses color pair #{fg}, #{bg} (key #{id})"

sup loads with that as well, and displays some color, but most of the screen
is unreadable (I'm guessing it's displaying as white text on white
background).

Any ideas?  I tried changing more things from Curses to Ncurses, but that
quickly started generating method undefined errors.

Thanks!
Dan
