[DerelictAlure] Error loading libdumb.so etc...

[Jack via Digitalmars-d-learn]

I've configured dub to build DerelictAlure for my project which
only contains the example code shown in:
https://github.com/DerelictOrg/DerelictALURE

The build was successful though when I tried to run it, they were
spewing out that they need some sort of .so files. Full error is

Though it says that once you configured dub to automatically
build your projects, it would automatically link libraries,
etc... http://dblog.aldacron.net/derelict-help/using-derelict/

In case it helps, this is my current dub.json file:
http://npaste.de/p/Go/

I've already installed openAL and alure in my system in hopes of
solving the issue.

So erm, any clues? Did I miss anything?
I'm using an ArchLinux x64 distribution inside VirtualBox.
