Install BackupPC on Readynas NV+

I've had a slightly different experience with installing backuppc on a Readynas Duo. My best attempt has been as follows:

1. Install togglessh, enablessh and apt.
2. SSH into the NAS, and enter the following:

apt-get update
apt-get --reinstall install perl perl-base perl-modules perl-doc
apt-get install backuppc

This failed as follows:

/var/lib/dpkg/info/backuppc.postinst: line 83: htpasswd2: command not found
Starting backuppc: 2009-08-10 06:54:24 $Conf{NmbLookupPath} = '/usr/bin/nmblookup' is not a valid executable program
invoke-rc.d: initscript backuppc, action "start" failed.

So I too cannot find htpasswd2, but the installer has successfully created the backuppc user.

Looking into the lack of nmblookup, dpkg -l | grep sa?mba? reveals:

So there is obviously a "special" version of smbclient that doesn't include nmblookup. This is a bit of a pain, because this is how backuppc finds machines to back up.

Q1: Does anyone have ideas as to where I can find (or in desperation compile) nmblookup?

Weirdly, when I start backuppc manually (using /etc/init.d/backuppc start), I get a different error:

Starting backuppc: /usr/bin/perl: relocation error: /usr/lib/perl5/auto/Compress/Zlib/Zlib.so: undefined symbol: Perl_Gthr_key_ptr

Q2: How do I solve the zlib problem?
