[R-sig-Geo] rgdal package installation error

[Siva Sundaresan]

I am trying to install the rgdal package under Ubuntu 8.10 with have 
gdal 1.7.2 installed. I get the following error:

On typing:

 > install.packages("rgdal")

I have tried uninstalling and reinstalling gdal (using sudo apt-get 
install). I have also tried downloading the rgdal tar.gz file and 
installing using R CMD INSTALL at the shell prompt. I still get the same 
error message as above.

If anyone can help me, I would be very grateful.

Thank you,
Siva
