[KDE/Mac] kde4 on Tiger using macports

[Jonathan Stickel]

I have (finally) built and installed kdebase4 using mapcorts on Tiger 
(10.4.11).  However, nothing runs correctly (if at all).  kwrite is very 
slow and ugly.  More importantly to me, dolphin will not start at all. 
I try to start it two ways, and I get

$ open -a dolphin
2008-12-23 09:39:58.684 open[24306] Couldn't launch application:  (null)

$ /Applications/KDE4/dolphin.app/Contents/MacOS/dolphin
(...prompt returns with no message, and then...)
<unknown program name>(14342)/: KUniqueApplication: Cannot find the 
D-Bus session server

Not much for me to go with here.  I do have dbus-daemon running.  Any ideas?

Thanks,
Jonathan
