No, I tried.

I have also tried to start python -vv.
For _delaunay I get a correct import.

# trying C:\Python26\lib\site-packages\matplotlib\_delaunay.pyd
import matplotlib._delaunay # dynamically loaded from
C:\Python26\lib\site-packages\matplotlib\_delaunay.pyd

For _path and _image I get

>>> import matplotlib._path
# trying C:\Python26\lib\site-packages\matplotlib\_path.pyd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.
>>> import matplotlib._image
# trying C:\Python26\lib\site-packages\matplotlib\_image.pyd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.

So Python checks the right place but then concludes that the DLL is not
there.  I guess something goes wrong with the linking, but in fact I do not
know how to write a DLL for Python and I'm stuck now.
I have checked that the compilation was ok and the rest of the installation
(GTK+ etc) is ok.  I can import matplotlib itself.  In the packages I had
only one package to patch: I think "gpobjects" had a reference to "@FFI_LIB@".
This was getting through pkg-config and stopping the compilation, so I have
removed it.

... HELP! ;-)
