please compile Qt 4.5.0 with X11 Session Management support.
when doing configure make sure libSM and libICE packages are installed.

when you run qt configure with -v -sm, it will complain if 
configure is not able to add Session Management support and
also tell you which files are missing. Find out which packages provide
these files and install those.

$gmake confclean
$./configure -v -sm
....

Here is the config I use on Mandriva.  
./configure -v -confirm-license -prefix `pwd` -opengl -xrender -xcursor -xrandr -qvfb -openssl -fontconfig -sm

Here are the packages I need to install on Mandriva i586 (64 bit is slightly different) 
Note that other packages may be required, but they are already present on a normal 
Mandriva install. CentOs may be different.
