- Where did you get the minidlna-1.1.4? Was this from your attempt to build it yourself? If yes then you’re missing a lot of stuffs which why the program failed to run due to missing libraries. How to get them? You need to manually build them like how you did for minidlna-1.1.4, every each of them. They doesn’t get built automatically when you build minidlna-1.1.4 alone.
2-3) The ones you posted (and understood) seems extracted from the 64k build guide in this thread http://community.wd.com/t5/WD-My-Cloud/GUIDE-Building-packages-for-the-new-firmware-someone-tried-it/m-p/770653#M18650 and yes you should follow the OP’s guide in that thread to prepare the build environment.
