There are interdependencies between the R binary and the dynamically loaded
libraries it loads.  By upgrading R, you have agreed to the Faustian bargain
of potentially having to upgrade these libraries too.  

So reinstalling foreign from CRAN should do. R can do that for you, see 
	help("update.packages")
and make sure you also have r-base-dev installed as this will cover most if
not all of the tools

Hth, Dirk
