Instead of copying the shell script over, I created a symbolic link
from /usr/local/bin/R to /usr/local/lib/R/bin/R. This automatically
gets updated when I rebuild R. And if I put the new version of R
in a different directory and fail to update the link, then I notice
I've still got the old version as soon as I start R up.

Just my 2c tip.
