The code from kcachegrind.sf.net is quite old, and uses Qt 3.x. However, the current Qt version
is 4.x (newest one is Qt 4.7, included in the Qt SDK, as far as I know). You can not compile that
source with Qt4.

For recent KCachegrind sources compiling with Qt4 (and KDE4), check out the KDE source package
of Centos. There should be one called kdesdk or similar, providing the kcachegrind binary.
Alternatively, get the sources of a recent version of the KDE package "kdesdk", go into the
kcachegrind/ subdirectory, run "cmake; make" which should build the kcachegrind binary.

Best,
