Hi,

the command line and the config.log seems OK.

You probably need to update your installed libnftnl. I had a look in the
repo. and saw your undefined functions were added recently to the lib
with the following commit on 13.08.2014:

common: add batching interfaces

This patch adds the following new interfaces:

 int nft_batch_is_supported(void);
 void nft_batch_begin(char *buf, uint32_t seq);
 void nft_batch_end(char *buf, uint32_t seq);

Quite likely this is going to be reused by third party applications
requiring to put things in the batch. We already have potential clients
for this code in nft and iptables-compat.
