I first had the problem with cups-1.1.22-source.tar.bz2 when updating
the cups port.  I had corrupted files from several ftp sites and I
remember that the file sizes were different each time.

I just used 'fetch' to get the same file and it is corrupted once again,
but the filesize is correct this time.  I'd be happy to send you the
file but I have no ftp server available to me.  May I upload it? (8MB)

I just tried this and, with a sample size of 1 try, it works fine.  I
changed the value of sack while my newsreader was open to this group
and it got very confused -- I had to close the newsreader and reopen
it before I could post this.  Dunno if it's related to sack or not.
