Anyone else seeing this problem?:

The 'distinfo' for mozilla contains *all* incorrect SHA1 hashcodes
for the patch files, like this:
a# cat distinfo
$NetBSD: distinfo,v 1.56 2004/06/01 15:01:17 taya Exp $

But if I generate the sha1 hashcodes myself I get these
completely different results:

Oddly, the hashcode for mozilla-source-1.6.tar.bz2 is correct.
