Hi,

Check the dates for a version current when 2.7.1 was current and maybe get 
more recent. Do the same with sp if it complains - the most recent one 
needs >= 2.9.1

Hope this helps,

Roger

PS. Debian policy is very odd, R is three stable releases on from there, 
maybe ask on the R-sig-deb (or similar) list.
