APM: Problem opening a file

[Evan Harris]

I'm getting the following error trying to open a file with perl tie DB_File:

ERROR: Unable to open access.db file '/etc/mail/access.db': Inappropriate
ioctl for device at ./relaydelay.pl line 1168.

Here's the code that generated it:

  if (defined $sendmail_accessdb_file) {
    my %accessdb;
    # Test that we can open the accessdb file
    if (! tie (%accessdb, 'DB_File', $sendmail_accessdb_file, O_RDONLY)) {
      die "ERROR: Unable to open access.db file '$sendmail_accessdb_file': $!";
    }
    untie %accessdb;
  }

Any suggestions on how to fix this?  As far as I can see, the file is fine,
I even deleted it and recompiled it.  The strange thing is it was working on
the same system a day or two ago, and AFAIK, nothing has changed on the
system as far as perl/libs etc.
