I installed macports following procedures on their site, issued
sudo port install kdenetwork4(kde version is 4.4.x).
I also wrote simple Portfiles for kdevelop 1.0.2., but couldn't run a dbus session using the command given me in the terminal after each kde package install. To fix this i edited /Library/LaunchAgents/org.freedesktop.dbus-session.plist and changed OnDemand and Disabled options in it to the opposite values.
Unfortunately KDevelop crashed after i tried importing a project (you can see the backtrace on the screenshot). Other apps like KTorrent, Kopete, Lokalize are usable (although being a little ugly in the terms of appearance).
