Remember to read very carefully the Qt readme before starting.  Install your 
Qt4 to a different directory to your system Qt, for 
example /usr/local/lib/qt4. Then when you are wanting to build or run 
programs against that new qt, set the variable $QTDIR to the location of your 
new Qt, and add $QTDIR/bin to the $PATH. You may also need to set 
$LD_LIBRARY_PATH to $QTDIR/lib or add it to /etc/ld.so.conf. If you are 
wanting to run or build applications against the old Qt, use your old 
settings for these variables.
