Unable to run D program on mac system when using dependency.

[Harbeer Kadian via Digitalmars-d]

I am pretty new to D language. I am working on existing code 
developed by others. Previous developers were using linux 
environment to build and run the D Application.
I am trying to do the same in MAC as it is my local environment.
Here is how my jub.json file looks like
{
        "name" : "dsmasher",
        "description" : "Hello World - A minimal DUB bundle.",
        "dependencies" : {
                "d2sqlite3": "~>0.9.7",
                "botan": "~>1.12.9"
        }
}

The program is very simple
import std.stdio;

int main () {
   return 0;
}

But when I build it throws following errors.

/Library/D/dmd/src/druntime/import/object.d(3440,23): Error: 
template memutils.refcounted.RefCounted!(X509CertificateImpl,

I am using dmd compiler for this.
Please help if you have any idea.
