FWIW I did manage to get it using darcs (!) having not checked the  
wiki to see that it was supposedly impossible these days.  (Well, I  
did get --partial.  --all is a definite mistake.)

Mine stopped at array.  That said, it does seem really slow; given  
your comment about downloading, this sounds like a problem with  
darcs.haskell.org in general.  But it might be worth grabbing darcs1  
for Leopard and trying again.
