supping the ports for 4.11

[Pete French]

I understand that recent changes mean that when I cvsup the
ports I also need to do a 'make fetchindex' to get the index
file right ?

But that will give me the most recent index file will it not ?
So if I am supping the ports with a tag of  tag=RELEASE_4_11_0
to get the 4.11 ports, how do I fetch the index file that goes
with them ?
