%> ruby --version

ruby 1.8.6 (2007-03-13 patchlevel 0) [powerpc-darwin8.9.0 ]

and i'd like to try Ruby/Tk (for Arcadia afterwards) however i get :

`gem_original_require': no such file to load -- tk (LoadError)

with a simple Tk example.

what do I need to do in order to get Ruby and Tk working together on 10.4.11 ?

best,
