Good that you have found the solution of the problem. Though I wouldn't  
have expected the path '/usr/lib/qt/include' to mess up things. I will  
look up what google & Co say about CPLUS_INCLUDE_PATH. Maybe we can  
indeed add a check to configure. If you have a concrete idea please  
submit a patch - I'm not very gifted if it comes to autoconf & Co.
