I usually just install the new version over the old one (to the same
folder), then 
update.packages(ask=FALSE)

This particular upgrade required
update.packages(checkBuilt=TRUE,ask=FALSE)

I do this way since R version 1.6 (or even 1.4), and everything works fine
and smooth.
Sometimes I have to manually delete older README's or something like this.
