Unable to compile Phobos using wiki's instruction

[Geod24]

Hi folks,
As I'm learning phobos, I wanted a more inside look and did a co 
of the libs + dmd.
DMD compiles fine (using dmc), as well as druntime.
But when it comes to phobos, I'm not able to compile, I get:

[...]

G:\code\D\dmd2\src\phobos>

I tested on 2 computers (win7 64b).
1) I tried win32/win64, using both the built compiler (DMD 
2.064-devel) and 2.63.2 downloaded from the website. I have VS 
2010 as well as 2012 installed.
2) I tried win64, using only the devel compiler. I also tweaked 
the Makefile (Setting C:\ instead of \ for the SDK / VS path, and 
setting VS version to 11 as I only have VS2012 installed).

For the rest I stricly followed 
http://wiki.dlang.org/Building_DMD (I even have %DM_HOME% in my 
user's env).

Any help will be greatly appreciated, as I'm pretty sure I am 
missing the obvious.
