I believe on the Mac a 3 button mouse will behave the same as on other
platforms.  The standard vtk interactors seem to expect you to have such
a mouse.

Well, I've never used Tcl/Tk so I'm not sure if the problems you are
seeing are related to bug 2025 or not, but the symptoms sure sound the
same.  Have you tried a C++ VTK example?

>/Systems/Library/Frameworks/tk.framework and the real directory is
>Tk.framework with "T" in uppercase although ccmake chose it automatically).

Interesting find!  I see the same problem on my dashboard machines. 
This is a cmake/vtk bug I guess.  I believe it would prevent things from
working properly on case-sensitive file systems, but by default Macs are
formatted with case-insensitive (but case-preserving) file systems.  I
just filed bug 4572 for this.
