I've seen this error on a couple of occasions, mostly involving large
packages, too. It is not specific to gcc42. I've seen it both on ppc
(Mac Mini ppc) and on i386 (Mac Mini core duo), but never on my
MacBook Pro (core 2 duo). Sometime it happened twice in a row, the
next day it worked fine. I have no idea what the root cause could be.
IIRC, I saw this error message also before the latest tar 1.16.1-1
was released, but the older tar did not fail in these cases.
