Thanks for tracking these:

The resolution for issue 1 seems OK to me.

I think you can replace this with:

      52 #if   PY_VERSION_HEX >= 0x02030000
      53 #define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED \
      54   0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,
      55 #elif PY_VERSION_HEX >= 0x02020000
      56 #define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED \
      57   0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0,
      58 #else
      59 #define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED
      60 #endif

#if PY_VERSION_HEX >= 0x02060000
#define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED \
   0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,0
#elif PY_VERSION_HEX >= 0x02030000
#define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED \
   0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,
#elif PY_VERSION_HEX >= 0x02020000
#define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED \
   0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0, 0,0,0,0,0,
#else
#define VTK_PYTHON_UTIL_SUPRESS_UNINITIALIZED
#endif

and try if that fixes it.  I haven't yet moved to 2.6 to know if that 
will work.

Thanks.
