[R] failed to load MASS at start up

[Michael Na Li]

Just installed R-1.7.0 (with recommended libraries) on RedHat 8.0.  
At R console, I can do

> library (MASS)
> 

just fine.  However, if I put a line 'library(MASS)' into ~/.Rprofile, it
fails to load,

R : Copyright 2003, The R Development Core Team
Version 1.7.0  (2003-04-16)
....
Type `q()' to quit R.

Error in get(x, envir, mode, inherits) : variable "biplot" was not found
Error in library(MASS) : package/namespace load failed
[Previously saved workspace restored]

What's happening?  I also tried to load 'lattice' (which I assume is where
biplot is defined) before 'MASS', but got the same error.
