[vtkusers] VTK Python on Sun Solaris

[Andy Cedilnik]

I suspect you are using Sun's C++ compiler. 

The problem is simple; some of the static constructors of C++ classes
are not called in the right order because Python is being build with C
compiler and not C++. So, the solution is to use vtkpython, which is yet
to be made. There is a pore attempt of mine in VTK/Wrapping/Python, but
does not work just yet. I will finish it once I have some more time.

What you can do for now, is to look at that file and try to compile it.
It is called vtkpython.cxx.in. You will have to modify the CMakeLists
files just a bit.
