I'm making my sup gem using ruby1.9.1 and the latest code from gitorious.
The code compiles a gem without complaint, but the gem doesn't install and
gives the above error. When the Rakefile is updated to refer to ncursesw not
ncurses, the gem compiles, installs, and runs without a problem.

Best,
Neil.
