First of all, why do you think you (her?) need a box,
or even rbldnsd?  If you're using CBL (as you mentioned
below), or DSBL, or whatever, it should be ok to use any
similar blocklist as described, by performing direct
queries to official nameservers, without setting up
your own "caching" rbldnsd.

"blocked" or "blocked.txt" ? ;)

Hmm.  what's the *exact* content of line #2?

wow.

And it loaded no entries at all.  Hmm... let me guess...
How about line endings?  Are lines ending with bare
linefeed as usual on unix, or with <cr><lf> as on DOS?

What's that 127.0.0.1:... supposed to mean?  In previous example,
you used a zone name here, as it should be.  I don't think
127.0.0.1 is a good zone name...

So it can't find the file named `blocked' in directory
/usr/local/etc/rbldnsd .  Where it is?  Maybe it's called
"blocked.txt" instead?

And finally, what does your subject mean?  I thought you're trying
to run rbldnsd without bind on a machine and are having some probs
with recursive resolving... ;)
