R help - Mar 2010 - Problem with package fpc

I am trying to load package fpc in order to use the 'plotcluster'
function
   however everytime I attempt to do so I get the following warning message:



   > library(fpc)
   Loading required package: MASS
   Error: package 'MASS' could not be loaded
   In addition: Warning messages:
   1: package 'fpc' was built under R version 2.9.2
   2: In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc   
lib.loc) :
     there is no package called 'MASS'



   I thought that MASS was one of the basic packages supplied with R but when I
   look in the library I cannot find it.

   However in windows programme documents under R there is a folder called
   MASS.



   Could somebody tell me where I am going wrong?



   Thanks in advance,

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.
