I don't remember any rending and tearing, but I do remember objections 
to modifying the path during installation.  I wouldn't want to write 
code to do that, because it's hard:

- Most people don't want to put R first, because it may hide something 
important.

- Putting it last won't work if an earlier version is already there.

So you need to examine the path and correct it, an automatic change is 
unlikely to be successful.

But if you want to write code to do that, just go ahead and do it.  Put 
it in a package, even.
