Actually, it looks like you have problems setting up vim (or maybe with an outdated version of vim) - everything works fine for me. I have vim 7.3.346 packaged for Debian. The standard ruby ββsyntax files and the syntax files from vim-ruby do the job. If the update is not an option or does not help to attach the output of the syntax and: script commands. Here's a tip on how to simplify the process.
