 From the CRAN Ubuntu README:

 >>>
Installation and compilation of R or some its packages may require  
Ubuntu packages from the "backports" repositories. In particular, this  
is the case for Tcl/Tk 8.5 on Gutsy and Hardy. Therefore, it is  
suggested to activate the backports repositories with an entry like

deb http://<my.favorite.ubuntu.mirror>/ hardy-backports main  
restricted universe

in your /etc/apt/sources.list file. See http://www.ubuntu.com/getubuntu/downloadmirrors 
  for the list of Ubuntu mirrors.
