it did not in the past, now it is included. 
the Gems repository does not have ri, (I'd like it to be there anyway,
but ATM it is little useless, given that ri is in ruby's cvs), and it
used to do some silent pattern match on the requested gem, this is the
reason you goit labyrinth.

Anyway, you can look here:
