This will be from the first fetch you had with the old checksums.

Once a file has been successfully downloaded and checksums matched once (and 
the .done file has been written), they won't be checked again for that file. Did 
you perhaps update the checksum in one of the gcc recipes and not some of the 
others? If so, that would explain this situation.

Cheers,
Paul
