Building fails using VisualD; works under dub

[ShadoLight]

Hi,

After a long absence I am returning to D.

So I see we now have dub as package manager. Nice!

So I create a new package (dub init sample1) and pull in a 
dependency (dlangui).   Then modify the source to use the dlangui 
lib. Dlangui pulls in some Derelict and X11 dependencies, but all 
works as expected. Nice!

Then I generate a VisualD solution (dub generate visuald), and 
try to open + build the same project from VS. The solution opens 
fine and editing works fine, but fails to build with:

Building f:\MyProjects\D2\VC2010\Dub\sample1\sample1.exe...
cannot monitor 64-bit executable dmd, no suitable tracker.exe 
found
Building f:\MyProjects\D2\VC2010\Dub\sample1\sample1.exe failed!
Details saved as 
"file://F:\MyProjects\D2\VC2010\Dub\sample1\.dub\obj\

This just shows the error for the exe, but all the 
Derelict/Dlangui libs also fail to build with an identical error:

Building lib\dlangui.lib...
cannot monitor 64-bit executable dmd, no suitable tracker.exe 
found
Building lib\dlangui.lib failed!

The "cannot monitor 64-bit executable dmd" is a bit confusing... 
as far as I can see DMD is in fact a 32 bit exe. And I have no 
idea which "tracker.exe" it is looking for.

I am running on:
Win 7 x64 bit
DMD v2.077.1
Visual Studio 2010 (x32 bit)
VisualD 0.46.0

I'm a bit stumped at this point.. any help will be greatly 
appreciated!
