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

[Dominik Szczerba]

Hi David,

Thanks, indeed, there was no PYTHONHOME set. But setting it brings me
only one step further. The next is the error when calling "import
vtk". See the error at the end. I saw a similar thread when you wrote
it is about mixing release and debug for python. It is not the case
here, both python and vtk is self compiled with the same compiler
settings (Release). I blind tried various combinations of PATH and
PYTHONPATH to no avail. I will be happy about some more ideas to try.

Regards,
Dominik
