Thanks Prof Ripley, and Kjetil too, for your help. I am sure this was obvious to anyone but me, but I found the wording in

a bit confusing. May I suggest that where it says ``To get the very latest version, use update.packages() from an R session'', it could be added: ``Note also that the current version of your R base system may limit the update, i.e. if the R base system you are running is too old, you will not be able to get the latest version of MASS. You can check the dependencies of MASS from the <a
href="">Description file of VR at CRAN</a>''.

And maybe right before ``As the VR bundle is now recommended'' it could say ``MASS does not have its own package, but comes bundled with other libraries in a package called VR. Thus if you want to use/update MASS you need to install/update VR''.

Searching a bit more I have found that this problem has been brought up in the ubuntu forums

i.e. that the GNU R version is too old. As a temporal fix, it is suggested to install the sarge .deb packages from and then Linux/debian/stable, overlooking the dependencies error with libc6.

I'll update to 2.2.0 in a week, but for the moment I did the former and it seems to work with the code I was writting.
