I'm attaching a couple of things I've got sitting around but that aren't
ready for release yet that might help you. The first works like this:

   my $dbh = DBI->connect('dbi:AnyData(RaiseError=1):');
   my $AoH = [ { id=>1,phrase=>'foo' }
             , { id=>2,phrase=>'bar' }
             ];
   $dbh->ad_import('t','Hash',$AoH);
   print "ok!" if 'foo' eq $dbh->selectrow_array("
       SELECT phrase FROM t WHERE id=1
   ");

With some modification, it could automatically read a text file, use
eval to turn it into a hash and import it, then on export use
Data::Dumper to print it back to file.

The second attachment should parse and import Ini files with sections
and even preserve comments within the Ini files.

Neither is ready for prime time. If you (or anyone else) wants to take
on authorship of these, please do!

It looks to me like dhcpd.conf format can include an unknown level of
nesting so it's not a good candidate for importing into strict database
table format. Also, it looks rather hairy, have those guys heard of
YAML? :-) But if all you need to do is parse a subset of dhcpd rather
than the whole syntax, my suggestions may help. Also if there's a dhcpd
parser out there, it would be simple to write an AnyData::Format plugin
that used the parser. If that's a direction you want to go and you need
hints, let me know.
