Looks to me it is the done causing your problems.  Typical syntax is :-
for f in `ls` ; do
  something
done

Nup; just chuck the code on the end of /etc/profile.  You should probably 
change the wait to a sleep 2 otherwise your message won't be visible.  You 
should also possibly bypass this code for select users (root might be a good 
one) and be sure to stay logged in while you are fiddling with /etc/profile 
(ie test it using a different console).
