Error 1: Previous Definition Different : _D3gtk3All12__ModuleInfoZ (gtk.All.__ModuleInfo)

After upgrading to latest dmd and having to rebuild gtk, I now 
get the following error

  Error 1: Previous Definition Different : 
_D3gtk3All12__ModuleInfoZ (gtk.All.__ModuleInfo)


in my apps that were previously working(no changes, opened up old 
app and tried to build it and it didn't work). All I did was 
upgrade dmd2.

So tired of D and it's crap ;/ So unstable in so many ways. About 
10% as productive overall than other languages I've used.  It's 
error messages are about as helpful as a rock.
