Sorry bad habit of typing replies when doing something else and not
proofreading before sending -- my bad.  Meant to say that you may have to
chase where you system (re-)sets and overrides in case changing the value
in Renviron.site does not propagate.  Also make sure you test on fresh
sessions so something like

   edit somefile
   Rscript -e 'print(.libPaths())'

is recommended as the file change will never alter a running session.
