Issues with GTK backend on windows

Hi all,

I have developed a little GTK program which uses Matplotlib to render plots. Now it is done, I would like to distribute for both Linux and Windows platforms but, to make things short, I have some troubles to get matplotlib work with GTK backend on Windows.
Basically, here is what I get when I try to use GTK backend with matplotlib:

>>> import matplotlib
>>> matplotlib.use("GTK")
>>> from pylab import *

Traceback (most recent call last):
   File "<pyshell#2>", line 1, in <module>
     from pylab import *
   File "C:\Python26\lib\site-packages\", line 1, in <module>
     from matplotlib.pylab import *
   File "C:\Python26\lib\site-packages\matplotlib\", line 253, in <module>
     from matplotlib.pyplot import *
   File "C:\Python26\lib\site-packages\matplotlib\", line 75, in <module>
     new_figure_manager, draw_if_interactive, show = pylab_setup()
   File "C:\Python26\lib\site-packages\matplotlib\backends\", line 25, in pylab_setup
   File "C:\Python26\lib\site-packages\matplotlib\backends\", line 25, in <module>
     from matplotlib.backends.backend_gdk import RendererGDK, FigureCanvasGDK
   File "C:\Python26\lib\site-packages\matplotlib\backends\", line 29, in <module>
     from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array
ImportError: No module named _backend_gdk

Here is my configuration:
Python: 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] (as given by sys.version)
pygtk: 2.12.1
gtk: 2.16.1
matplotlib: (installed using windows installer from sourceforge)

It seems to me that the matplotlib version provided was no built with GTK support (since there is no _backend_gdk.pyd present), am I right or did I miss something?

Based on this assumption, I tried to build matplotlib from source... Everything went just fine until mingw tried to link this nasty _backend_gdk.pyd.
The following command:
C:\MinGW\bin\gcc.exe -mno-cygwin -shared -s build\temp.win32-2.6\Release\src\backend_gdk.o build\temp.win32-2.6\Release\src\_backend_gdk.def -Lwin32_static\lib -LC:/GTK/bin -LC:/GTK/lib -Lwin32_static\lib -LC:\Python26\libs -LC:\Python26\PCbuild -lpython26 -lmsvcr90 -o build\lib.win32-2.6\matplotlib\backends\_backend_gdk.pyd

actually ended in:
build\temp.win32-2.6\Release\src\backend_gdk.o:backend_gdk.c:(.text+0x18d): undefined reference to `gdk_pixbuf_get_type'
build\temp.win32-2.6\Release\src\backend_gdk.o:backend_gdk.c:(.text+0x19f): undefined reference to `g_type_check_instance_cast'

collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1

I really have no clue on this one... I must have forgotten something but I don't get what!

Has someone got an idea?
