On Windows,
you also can use Gabor Grothendieck's copydir which is part of his utility set batchfiles available in the "Other" part of CRAN. It copies all packages which are available in a source tree but not available in a target tree from the source tree to the target tree.
Then you still have to do update.packages(checkBuilt=TRUE).
