Good question, I'd like to know this myself!

Any Mac experts out there who can help us? Are the extra paths in /etc/ 
paths.d/ included alphabetically (by file name)? I suppose it's  
intentional that they go _after_ the standard system directories,  
otherwise you might mess up your OS X installation pretty badly ...

It's obvious where you get the $M2:$PATH from -- that's what you've  
specified in environment.plist. I don't know where /usr/local/bin has  
been added, though. Perhaps something that R does automatically so you  
always have access to the GNU Fortran installed with R?

Well, they're set in your environment.plist file above. When you start  
R.app, it gets its environment variables from this property list,  
while the Terminal uses the "normal" .bashrc-based mechanism and seem  
to ignore environment.plist.
