A possible extra point: if R CMD INSTALL is being run from 
install.packages() and that is being run from R.app, it is the PATH 
setting of the R.app process that is most relevant. I set mine in the 
~/.Renviron file to get consistency between different R invocations.

If you want to set an environment variable for all applications 
(Windows-style!) then

might be helpful.
