If you're not a developer, you will not be compiling it at any time. It's listed because it is something that is unique to this coin's code.
I am a developer, though not really a crypto developer.
I would be interesting in hearing about what properties of this code make it compilable on platforms that other cryptocurrency wallets are not compilable on.
I understand that VNL is apparently more energy-efficient in some way? One wouldn't expect that to affect compilation though!
The code is a complete rewrite of bitcoin and peercoin. It is not a clone like the VAST majority of cryptocurrencies.
Hop on IRC if you want to try to get more in depth.
