First, this applies only if you switch from Tiger build to Leopard  
build.

"The best way" depends really on your exact setup, but one way is  
something like this:

in your "old" R run:
a=.packages(TRUE); save(a,file="~/pkg.RData")

if you don't want to use your old R you can blow everything away, e.g.
RL=`echo 'cat(paste(.libPaths(),collapse="\n"))' | R --slave`
rm -rf $RL
rm -rf /Library/Frameworks/R.framework


Then install the new R and in the new R
load("~/pkg.RData")
install.packages(a[!a %in% .packages(TRUE)])

(If you don't blow away your old stuff and you have an unversioned  
custom library path, you have to use install.packages(a) to make sure  
old stuff gets overwritten)

Cheers,
Simon
