I've been looking at Bob Newell's package for writing poetry, poetry-mode (http://www.bobnewell.net/filez/poetry.el).
It's incredible, and the line-by-line syllable counter works great. Unfortunately, the rhyming dictionary doesn't work. Looks like the required command-line rhyming dictionary package (https://code.launchpad.net/ubuntu/+source/rhyme) is for Ubuntu.
Does anyone know how can I get it working on OSX?
