[R] Unable to load foreign after upgrade on ubuntu

[Van Campenhout Bjorn]

I am running R on ubuntu dapper.  The version that is in the ubuntu
repos is 2.2.1, so I decided to upgrade by adding

deb http://cran.R-project.org/bin/linux/ubuntu dapper/ 

to my sources.list, as advised on the web page.  After sudo apt-get
update and upgrade, I have version 2.3.1.  However, when I try to load
the library 'foreign', I get the following error:

Error in dyn.load(x, as.logical(local), as.logical(now)):	
Unable to load shared library
'/usr/lib/R/library/foreign/libs/foreign.so':
/usr/lib/R/library/foreign/libs/foreign.so: undefined symbol: isfinite
Error: package/namespace load failed for 'foreign'

What is going wrong?
