It was my experience yesterday with using the old method (copy folders to new 
../library/ and use update.packages(checkBuilt=TRUE) ) that I was given the 
option to have packages with more recent updates compiled from source. I had 
anticipated the issue (time) mentioned by Simon, so I only copied over perhaps 
a third of my full complement of packages.
