I do manually version-install almost as suggested for the dept copy (I
would use /usr/local/lib/R/1.2.3 in the way that ghostscript does),
which is why I know I need to manually migrate the packages.

One can of course install packages in a private library.  For my own
installations I do, but it is not seamless, not least from the
version-incompatibility of installed packages (and also that --vanilla
stops the private library spec being picked up from .Renviron).
