Just a guess, but when I was playing wit -CURRENT on my newer macbook
pro with the core duo I was getting a lot of fails in buildworld at
random times like you are seeing and it took me a while to figure out
my system time was way off.  make will give a lot of problems if your
time is off, especially if it is in the past.
