I think I found the fly in the ointment, running the same text3d() lines with 'useFreeType=TRUE' returns: "FreeType not supported in this build"
You need to install FreeType and FTGL. I think this is how to do it on Trusty. Don't know if it will work on your Ubuntu version.
sudo apt-get install libfreetype6-dev
sudo apt-get install libftgl-dev
and then reinstall rgl from within R using
install.packages("rgl", type="source")
