Yes, I compiled the C++ example and it works, but under Tcl, and with Tk
commands don't. Extrange!.

However I found a "solution". I compiled vtk with Carbon (ON) instead
Cocoa (OFF), and I changed the "t" by "T" in the tcl/tk cmake
configuration, and finally the interactor works, and I can use TkWidgets.

Now, I have only a path problem because when I run the vtk command
outside the /vtkBin/bin folder it gives me an error like it isn't able
to load dylibs (even when I have declared the LD_LIBRARY_PATH pointing
to the folder where the dylibs are). The same happens if I double-click
vtk in the finder. I think that this is resolved if I create an ".app"
for Mac.

Thanks.
