qt3 and qt4 do not generally conflict.  The headers and libraries are different. 
  What does conflict is the names of the binaries, particularly qmake.  When 
building, make sure your PATH variable has the right qt/bin path first.

You may want to look for the /opt/qt symlink and adjust /etc/ld.so.conf to point 
to the real libraries and not the symlink.
