I did some more work last night.  I recompiled pdns to use both the gpgsql
and the gmysql backends.  Results are inline.

Another recompile resulted in the same thing.  Again, not an issue for the
list, just noting.

Definining receiver-threads still results in pdns throwing an error, saying
it doesn't know the parameter 'receiver-threads'.

Using the gmysql backend still results in this.  Using the gpgsql backend
gives me clean and expected behaviour.  As pre my previous note, I don't
have any dynamic modules laying around.  The only thing I can think of is
the MySQL libraries on the pdns machine are 3.23.55, and the MySQL daemon is

Yep, this is still happening as well.  I verified this a number of times
last night.  However, localhost can now do recursion (it may have just been
a mixup on my part initially).

It turns out that my SQL tables were rather incomplete.  I've created the
tables as per doc.powerdns.com (*EXCELLENT* documentation!), and have
successfully started pdns with my domain as MASTER instead of NATIVE, now I
just have to actually test it...  :)
