QtD fails to build on Arch Linux

[w0rp]

I am very interested in seeing some updated bindings for Qt in D. 
I would even like to contribute to a revival project in some 
fashion. (Even though thinking about how bindings for Qt's 
classes and macros work makes my head spin.) My best experience 
in producing a GUI application thus far has been with Python and 
PySide. I think strong and up-to-date bindings for Qt in D could 
make GUI application programming even nicer than GUI programming 
in Python. This would be very good for D's PR.
