What happens if you start R, say library(rgdal), and try to do - say - 
example(readGDAL)? If the same happens, then most likely rgdal was 
installed before the system upgrade, and you now have g++4, meaning that 
the dependencies of rgdal (or GDAL as a whole) are no longer met.

If library(rgdal) fails as I suspect, you'll need to re-install it:

install.packages("rgdal")

ought to be enough, though GDAL may also need to be re-installed (all C++ 
programs are sensitive to build train upgrades, much more so than C 
programs). You may also do

update.packages(checkBuilt=TRUE)

which will freshen all the installed packages built with R < 2.6.

If rgdal itself works, then sorry, no idea. Maybe somebody on the list 
(STATGRASS, R-sig-geo) may have seen something similar. How were R and 
GDAL installed, from source? What does g++ -v say?
