You are right it's not a sup issue. Ruby ncurses hasn't been ported to
1.9 so I just used ncursesw which seems to work quite well. Since you
are using gem to install sup you will need to untar the gem file modify
the metadata, tar it all up and reinstall. Something along the lines of:

cd /var/lib/gems/1.9.1/gems/cache/
mkdir tmp; cd tmp
tar xf ../sup-0.11.gem (ignore any timestamp errors)
vi metadata (make sure you use vim which will deal with the compression)
tar cf ../sup-0.11.gem .
cd ..
gem install sup-0.11.gem
rm -r tmp (assuming it works)

If you have problems working out which line to change in the metadata
you could unzip it and apply the following patch:

--- metadata.old        2010-04-08 23:10:27.363603950 +1000
+++ metadata.new        2010-04-08 23:11:09.479559396 +1000

And that should do you.

Or you could download a modified gem from http://stuff.roughage.com.au/sup-0.11.gem.
That gem was built from git and works (on my machine!).

William, is there any reason you are using ncurses and not ncursesw?
