You have to change to code!
I think it just in vtkQGLInteractorWidget.cpp. I send you a patch for 
src/tkQGLInteractorWidget.cpp.  If I remember correctly these are the only 
changes I made. 
The second patch is for Linux systems (or gcc in general???). The patch makes 
the Makefile make a "better" shared library. You have to add the "-fPIC" flag 
to CFLAGS in include.make, too (no patch for that as you have to edit that 
file anyway). With the unchanged Makefile  I had problems with the "ldconfig" 
command.


Cheers
