Just to test, I downloaded the demos from http://www.ugcs.caltech.edu/~rise/tk-demos/ , installed the libraries libtcltk-ruby and libtk-ruby, and tried "ruby hello" and a little window appeared with the message "Hello Ruby World!". So I can't reproduce your problem. I suppose you installed the needed libraries? And I suppose you didn't miss the little window ;)? You can try with "ruby -d hello" to see what the interpreter is doing.
