portsnap fetch corrupt

[Alain G. Fabry]

Hello,

Whenever I try to do a portsnap, it tels me metadata is corrupt.

harley# portsnap fetch update
Looking up portsnap.FreeBSD.org mirrors... 5 mirrors found.
Fetching snapshot tag from portsnap5.FreeBSD.org... done.
Fetching snapshot metadata... done.

Fetching 3 metadata files... /usr/sbin/portsnap: cannot open d0fcac86ce12456d1bf6a63b3628725c24ea32d3e98d7d71280a7a9999681e17.gz: No such file or directory
metadata is corrupt.


I've already removed /var/db/portsnap directory, and redo the portsnap fetch, but the problem remains since several days now. 

What can I do to get this going again?

Running FreeBSD 8.1-RELEASE #0

Thanks,

Alain
