Cannot build ws2_32.lib

[Andre Tampubolon]

I found this code from this page:
http://rosettacode.org/wiki/Category:D

import std.stdio, std.socket;

void main(){
     writefln("%s", Socket.hostName());
}

When I tried to build it (I'm on Windows, anyway), I got this:
C:\Users\CSL-NB-064\Codes\D>dmd hostname.d

ws2_32.lib
  Warning 2: File Not Found ws2_32.lib
C:\dmd\lib\phobos.lib(socket)
  Error 42: Symbol Undefined _WSAIoctl at 36
--- errorlevel 1

I did some Googling, and I found this 
http://www.digitalmars.com/d/archives/c++/2519.html. It looked 
interesting because MinGW, instead of DMC was used. So I downloaded Jan 
Knepper's implib, and extracted it into C:\dm\bin. This is my 
implib.ini: http://pastebin.com/iusxakcj

The next part is to build ws2_32.lib I copied ws2_32.dll from 
C:\Windows\System32 into C:\dmd\lib, and ran this command:
C:\dm\lib>implib /v /system /IC:\mingw\include /suffix ws2_32.dll ws2_32.dll

The output was:

Then I tried to compile once again, and the same error still happened.
Is there an easier way to get the importants libs?
