You misunderstand: if you rebuild as a local package, so use the same
Build-Depends you used for a R-only install and get all required components.
That is how it gets automated.

Well maybe you you do not like the six-month cycle of Ubuntu ... so maybe you
do not run Ubuntu.  

Or maybe you are looking a for volunteer to provide current backport of
Debian r-cran-* packages for Ubuntu. Maybe this is something you want to
start then?  ;-)
