[rbldnsd] rbldnsd and blackholes.us

[vz at B3.ca]

Hello,
I'm trying to set up rbldnsd using the blackhole.us zone file from
http://blackholes.us/zones/countries/countries.rbl
My server runs RHEL3 and I used rbldnsd-0.995-1.i386.rpm from Fedora.
When I start rbldnsd using the following command 

# rbldnsd -n -r/var/lib/rbldns -b127.0.0.1 -l logfile
countries.blocked.rbl:ip4set:countries.rbl.bak

I get the following messages:
rbldnsd: listening on 127.0.0.1/53
rbldnsd: file countries.rbl.bak(4): invalid or unrecognized special entry
rbldnsd: file countries.rbl.bak(7): invalid or unrecognized special entry

=====================================
The first 11 lines of the file:
# head -11 countries.rbl.bak
$SOA 3000 ns1.blackholes.us hostmaster.blackholes.us 0 600 300 86400 300
$NS 3000 ns1.blackholes.us

$DATASET ip4set @
127.0.0.2:127.0.0.2:countries.blackholes.us

$DATASET generic @
@ TXT "See http://blackholes.us/"
@ A 216.243.118.34

$DATASET ip4set af
=====================================

Is the file I get from blackholes.us not in rbldns format?
Any help is greatly appreciated.

My second problem is that the logfile, which I expect to be in /var/lib/rbldns
directory is empty, nothing is being written to it.
