Michael, I don't think there's anything about your library that suggests a dynamic dependency; as a user, I would be more surprised by a long pause for a planet install during operation than by a slightly longer installation when I first download the package. I suggest you require the rsound package directly, and either split your package in two to reduce dependencies or just live with a possibly unnecessary dependency. I guess it depends on whether clements/rsound is significantly bigger or slower to install than your package or not. Personally, as a Planet user, if I downloaded an Ogg Vorbis library, I would not begrudge it a dependency on an extra sound library for potential conversions.
