This was the info I lacked. Many thanks!
So in general for includes from other VTK subdirectories like e.g. 
Imaging/Hybrid/ I'd add vtkImagingHybrid to the DEPENDENCIES?

The way to use vtkSimpleCriticalSection seems to have changed. I had to modify 
the code to this:

diff --git a/Imaging/Hybrid/vtkPartialVolumeModeller.cxx 
b/Imaging/Hybrid/vtkPartialVolumeModeller.cxx
index eaa702b..3f1ab52 100644
--- a/Imaging/Hybrid/vtkPartialVolumeModeller.cxx

    this->NumberOfThreads = this->Threader->GetNumberOfThreads();

+  this->ProgressMutex = new vtkSimpleCriticalSection;
  }

    if (this->ProgressMutex)

  }

Is that the correct way to do it now in VTK-6.1.0?

Again, many thanks for Your help.
Roman
