Go to the 3.3.2 installation directory and issue "make uninstall". Or if 
you used an .rpm or such, look up how to uninstall with that. Then to be 
sure of things, go to 3.3.3 and "make install"

Done properly two versions can co-exist easily. One key point is not 
installing them to the same directory - so use the --prefix command to 
configure. Also see the suggestions about using GMXRC here
