Your installation is broken. If you do not have MASS in one of your 
libraries, you need to reinstall R.

Which R version is this? If R < 2.9.2, you may want to upgrade your R 
anyway.

If you have installed R-2.10.1, you may want to run

update.packages(checkBuilt=TRUE)

That means you are actually under some Windows and there is MASS in your 
library? Perhaps the installation is broken or you are looking into a 
library that is not known to R or the MASS in that library is compiled 
for a very different version of R.
