Problems with Net::LDAP::LDIF;

[Erik Ableson]

Summary of the environment :
perl5 (revision 5.0 version 8 subversion 1 RC3) running under Mac OS X 
with the stock perl  load.

I'm trying to run a dump extraction against a Sun Directory server, and 
instead of manually writing the output, I thought I'd use the 
Net::LDAP::LDIF; library instead of writing an entry to LDIF dump 
routine myself.  However, it's not happy with the environment right 
now.

use Net::LDAP;
use Net::LDAP::LDIF;
use Getopt::Long;
$ldap = Net::LDAP->new( $server ) or die "$@";
$mesg = $ldap->bind;
open (LDIFOUT, ">dumpsun.ldif");
my $ldif = Net::LDAP::LDIF->new(LDIFOUT, "a", encode => 'base64', 
onerror => 'die', sort => 1);

The code above results in the following error :
Can't locate object method "attributes" via package "Net::LDAP::Search" 
at /Library/Perl/5.8.1/Net/LDAP/LDIF.pm line 374.

Any hints ?
