It's not a change to Rtools, it's a change is to the build system in R: 
  it allows you to rename sort or find in your own copy of Rtools, and R 
will use whatever you specify.  You were informed of this when I did it 
in 2007, and I've mentioned it when the topic comes up here, most 
recently in the message quoted above.  That's a long time ago, so I 
don't remember if you tried it then, but I've never heard a complaint 
from anyone else that it doesn't work.
