[pygtk] gtk on vista issue

[Meitham Jasim]

import gtk gives me this error on the console
>>> import gtk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\lib\python2.5\lib\site-packages\gtk-2.0\gtk\__init__.py", line 48, in
 <module>
    from gtk import _gtk
ImportError: DLL load failed: The specified procedure could not be found.

and a small error window pops saying "The procedure entry point
xmlCtxtGetLastError could not be located in the dynamic link library
libxml2.dll"
I only get this error on win-vitsa, I never had such issue under win-xp.
Any suggestion? Do we have different GTK dlls for vitsa?
