Building GHC on Mac stops

[Kazu Yamamoto ( 山本和彦 )]

Hi,

I'm using GHC head (32bit) on Mac. Recently, building GHC head
stops:

----
% make maintainer-clean; perl boot; ./configure --prefix=/ghc-head; make -j3

One more "make -j3" finishes the building. I'm sure that this does not
happen before.

Are there any guys who get this problem?
