I have solved this problem by an ugly hack: commenting out the most parts of 
the /usr/include/linux/time.h.
But you can try other approaches suggested in debian bug: #220232.
You can also look at bug #220399.

I have had also some different problems in other part of the qtvision. Which I 
have solved with the next patch:

If you dont want to bother with it, then I can send you (in private) the .deb 
package I built, and it will maybe work for you...
