I wonder it works that far. It won't for me on Windows nor Linux, 
because system2 passes the whole thing shQuoted to the shell. Hence it 
is highly shell dependent what happens with the ill formed command.

Whay not specify --library= in R CMD INSTALL if you are calling it 
programatically from R anyway?
