Problems with 2.0b25

I'm having problems working with 2.0b25:

1. hypermail -m received -x -c spam.config -p

   I get:

        hypermail: Couldn't create lock file "received/.hypermail.lock".

   Shouldn't this read the configuration from spam.config and process    `received' like a mailbox in mbox format?

b) cat received hypermail -c spam.config -p

   This processes received, but

. ignores everything written in spam.config and
. overwrites files in `./archive' instead of appending new mails
     there

Is this the expected behaviour?

Regards,

        Joey
