I have both qt3 and qt4 installed, and I don't have any problem. I think  
it's matter of order. Does qt4 still has problem even if it has  
/usr/local/include in the last order? Like this:

-I/usr/local/include/QtCore -I/usr/local/include

I believe that it needs to be fix in *.pc files. The qt3 doesn't has  
QtCore, so I think it should be no problem.
