[R] segmentation fault when loading MASS library

[Tao Shi]

Hi, all:

There are two versions of R installed on our Linux cluster: 1.6.2 and 1.7.0 
and both of them have problems with the MASS library.

For the R 1.6.2, whenever I load MASS library by typing library(MASS), there 
is a "segmentation fault" and it automatically exit R.

For the R 1.7.0, for some reasons, there is no MASS library (there are also 
other libraries came with the R 1.7.0) are missing.  Since I know the MASS 
library should be part of the R 1.7 distribution package, I went to talk to 
the system administrator who installed R 1.7.  He told me that he didn't do 
anything special during the installation and he's also puzzled how this 
would happen.

Help...........
