fancyRpartPlot can't find rpart.plot

This is using the fancyRpartPlot example in rattle 5.07. Is there something missing from the example?

Need to update rattle to pick up this case and offer to load the package.

This appears to have been fixed already (tested on 5.0.16). Removing the rpart.plot package and then building a decision tree and then Draw results in a popup to request to install rpart.plot.
