why use qt 4.4.3? I think you can use the latest version (e.g 4.7.1) as well.

If you want to use the qmake based building system for V3D (i.e. you would run build.linux script), you need to install qt in the following way.

(1) tar zxvf "qt_whatever_version.tar.gz"
(2) cd "qt_src_folder"
(3) ./configure (or use "./configure -nomake examples" or sth similar)
(4) make -j8 (assume you have 4 cores on your machine)
(5) sudo make install (if you don't have root permission, then try sth else in ./configure by using --prefix option)
(6) set up appropriate PATH variable so that your system knows where to find the "qmake" command
(7) simply run "build.linux"

As you can see, the real V3D building step is just one command (i.e. step 7), all other steps are for QT setup. If you already have it, you can just run Step 7.
