[R] problems in loading MASS

[Prof Brian Ripley]

MASS is part of the standard R installation, as a recommended package.

I suggest you try re-installing R and not then trying to download a 
different version.

I would also suggest trying 2.5.0 beta at this stage in preference to 
2.4.1 if you do need to re-install R.

Beyond that, there is a list (r-sig-mac) for Mac-specific problems
(and this is an OS-specific problem).
