I think this means you need to install the oniguruma C library and its headers. You don't say what platform you're on, so it's hard to be more specific about how to do that. Alternatively, you could use Ruby 1.9.1 which has oniguruma built-in, as well as other features to make working with encodings easier (one of the main reasons for using Oniguruma previously). alex
