KUniqueApplication complains ' Cannot find the D-Bus session server'

[Hui Jin]

Hello,

I have following the PORTING-TO-DBUS.txt to build the kdelibs4 and
kdesupport, for dbus part, I emerge the dbus-0.62 in the system-wide.

$ eix dbus
* sys-apps/dbus
     Available versions:  0.23.4-r1 0.50-r1 0.50-r2 0.60-r3 0.60-r4 0.61 0.61-r1
     Installed:           0.62
     Homepage:            http://dbus.freedesktop.org/
     Description:         A message bus system, a simple way for
applications to talk to each other

I then restart the dbus, and start custom-built kopete:

kopete: ERROR: KUniqueApplication: Cannot find the D-Bus session server

Then I restart the computer, my uptime :-(.
Still no luck. Any suggestions?
