I am trying to compile elm for NetBSD 1.0, but I'm having a problem with
file locking.  When I start up elm, I get

        Waiting to read mailbox while mail is being received: attempt #0

... then it says

Timed out - removing current lock file...
Couldn't remove the current lock file /var/mail/viento.lock
** No such file or directory **

Does this make sense?  It thinks there is a lock, but as it says,
there is no such file.  What's going on here?  Does anyone else have a
config file I could steal?  Thanks...
