Just a further note on the resolultion of the ncurses issue.
"gem install sup" seems to be failing on ncurses. # gem install sup Building native extensions. This could take a while...

Results logged to /var/lib/gems/1.9.1/gems/ncurses-0.9.1/gem_make.out I get pretty much identical output from "gem install ncurses", so I suspect the problem is not even a sup issue. Am I doing something terribly wrong? All comments most welcome.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 @@ -32,7 +32,7 @@ type: :runtime version_requirements: *id001 - !ruby/object:Gem::Dependency - name: ncurses + name: ncursesw prerelease: false requirement: &id002 !ruby/object:Gem::Requirement requirements: 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?
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.
