(unknown charset) portsnap5 problem, portsnap error handling

Not sure which list would be best for this, so using current_at_.

$ portsnap fetch && portsnap update
Looking up portsnap.FreeBSD.org mirrors... 5 mirrors found.
Fetching snapshot tag from portsnap5.FreeBSD.org... done.
Fetching snapshot metadata... fetch:

Portsnap metadata appears bogus.
Cowardly refusing to proceed any further.

First, it seems that portsnap5 host is missing at least one important file.
Second, it seems that portsnap should detect this kind of problem a little bit
earlier.  No need to call sha256, mv, etc if fetch clearly failed.
(Not sure, perhaps this is fetch not returning an error code).
