Wei, MASS is actually distributed in a bundle called VR, which is on 
CRAN. VR as in Venables and Ripley, the authors of MASS (the book). The 
VR bundle contains MASS, nnet, spatial and class packages.

The reason MASS comes with your binary installation is that the VR 
bundle has Recommended status - and should therefore be available in all 
binary distributions.
