VibeCustomMain not working

[Jerry via Digitalmars-d-learn]

Hello, I am trying to use vibe with DMD 2.67, dub and windows.
But in some way the default main function is sneaking in my build 
system even when I'm using VibeCustomMain version.

Main file:

import vibe.vibe;

void main() {
   writeln("Hello world");
}


And dub file:

{
    "targetType": "executable",
    "versions": [ "VibeCustomMain" ],
    "dependencies": {
        "luad": "~master",
        "kxml": "~>1.0.1",
        "jsonizer": "~>0.5.2",
        "vibe-d": "==0.7.23"
    }
}


I also tried this on DMD 2.71, 2.69 with same results. And I even 
tryed passing in VibeCustomMain manually.

Any ideas?
