GTKD doesn't work too

[Fabian]

Hi
I've got already experience with Delphi so I want to start learning D 
using a GUI library. I've already tried to install DWT2 but the 
installation failed and so I decided to try out GTKD. It's no problem to 
build and install GTKD using dsss but when I try to build a sample app I 
get the following error message:

I'm looking forward to your answers and I hope you can help me.

Greetings Fabian
