Build from source failed at netatalk-3.0.5

[snowman]

Trying to see if I can compile from the source as an exercise.

Is there a docker container/VM image which we can used to build firmware?
That would be great.

On my Ubuntu 14LTS VM it blew up at linking miniDlna.
So I switched to:
Build machine: Ubuntu 12.04.5 LTS (GNU/Linux 3.13.0-32-generic i686) on virtual box

Using debian-build-image from
https://raw.githubusercontent.com/assarbad/build-asuswrt-merlin/master/debian-build-image

It failed @ netatalk-3.0.5
It's all greek to me :-( Any help/pointer is appreciated.
