Actually the version on CRAN is pretty old, so I'd recommend people do 
install it from source, getting the source from R-forge.  Since that is 
a development site the quality varies over time, but right at this 
minute I would say it is better than the CRAN version.

Re Santosh's error messages:  it looks as though the Mesa installation 
is messed up.  I'd recommend uninstalling it, making sure there's no 
remnant of Mesa anywhere, then reinstalling it.
