If you install contributed packages into a separate library tree, you 
can simply run update.packages(checkBuilt=TRUE) after an upgrade of R. 
And all packages you ever installed we be reinstalled to fit to the 
recent version of R you are running, if required.

Please see the R Installation and Administration manual.
