As already pointed out, as starting point you could compile the 
application e.g. within folder /tmp and then copy the executable 
to cgi-bin folder.
Please make sure it has executable flag.

dub build --single hello.d

The application could look like this:
#!/usr/bin/env dub

/+ dub.sdl:
     name "application"
     dependency "arsd-official:cgi" version="4.0.2"
     subConfiguration "arsd-official:cgi" "cgi"
+/
import arsd.cgi;

void hello(Cgi cgi) {                                             
                      cgi.setResponseContentType("text/plain");

     if("name" in cgi.get)
         cgi.write("Hello, " ~ cgi.get["name"]);
     else
         cgi.write("Hello, world!");
  }

mixin GenericMain!hello;

Kind regards
