portsnap: corrupt snapshot?

[Justin Meyer]

Hi all,

I'm doing a portsnap fetch here, and getting the following error:

Fetching 130 new ports or files... /usr/sbin/portsnap: cannot open
7a8a3197e659d87ca60f358e3ff663b12d3d33d33b4f607741b2847a4a35e2f1.gz: No
such file or directory
snapshot is corrupt.

.. and indeed,
/var/db/portsnap/files/7a8a3197e659d87ca60f358e3ff663b12d3d33d33b4f607741b2847a4a35e2f1.gz
just plain doesn't exist.

Can anybody tell me what's going on here, or how to fix it?

Thanks!
