Please file bugs on GitHub. It looks like you're using packages built on top of ggplot2 - in particular the maintainer of ggtern seems to have disappeared. Otherwise I'd highly recommend using packrat or similar so you can choose on a project by project basis when you want to upgrade selected packages.
