That's guaranteed by the R install scripts, just by following `Writing R 
Extensions'.  *If* it is not working for you, you are doing something 
which you are not telling us.

No, yes, your messages are not clear enough for your helpers.

Ah, but that is not what you actually said (an example of the lack of 
clarity).

I still don't know if you are imagining that there might be a problem that 
you want to write a package to avoid, or that you have a current problem. 
If the latter, please start again with the full details: which packages, 
the commands you used to install them, what happens and what the links in 
the html file concerned are.
