Thanks to nudging by Charles, I''ve put together a HOWTO for IronRuby on Mono, describing my setup. I''m using NAnt for now until Rakefile is fixed. All relevant files are on the following address (and will be as I update them). http://sparcs.kaist.ac.kr/~tinuviel/download/IronRuby/ I would appreciate any success or failure reports. -- Seo Sanghyeon
