[vtkusers] python (2.7) problems compiling with MSVC 2010 64bit

I have now manually copied everything from vtk's build
bin\RelWithDebInfo folder to python's bin folder and I have manually
copied Wrapping\Python\vtk to python's lib\site-packages folder.
Such treatment seems to work for python 2.6.7 (= "import vtk" works),
but does not work for python 2.7.1. Note, I have no python/vtk in the
system path and pythonhome and pythonpath are not set.
Am I hacking and this will not work the next release, or is the right
way to go? Why would 2.7 not work on Windows? Works on linux all
right.
Thanks for any more hints,
Dominik
