Yes, if capabilities(c("tcltk", "X11")) are not TRUE, (like trying to
install on a server with no X11 display set), then there is no automatic
fallback from R trying to start tcltk to show a list of CRANs. The same 
list is shown going to CRAN from http://www.r-project.org, so 
install.packages(c("sp","rgdal"), dependencies=TRUE, 
repos="http://cran.arsmachinandi.it/") or one of the other Italian 
mirrors should get you there. 

The help page for options says:

     'repos': The URLs of the repositories for use by
          'update.packages'.  Defaults to 'c(CRAN="@CRAN@")', a value
          that causes some utilities to prompt for a CRAN mirror.  To
          avoid this, use something like
          'options(repos=c(CRAN="http://my.local.cran/R"))'.
