KDevelop doesn't work.

[arrowdodger]

I've installed KDevelop using AppCafe?, but it doesn't work.
Shortly after showing splash screen i get a small window telling me that there is an error. I've been able to get that window's title:

Could not find KTextEditor::Factory, check your installation.
Make sure that KDEDIRS is set properly and that you ran kbuildsycoca4. – KDevelop

I've been unable to run kdevelop from konsole to see additional error messages, because kdevelop executable isn't in PATH and i haven't found it.

I've managed to run it from console.

First, i see a wall of messages like

kbuildsycoca4(47941) KBuildServiceFactory::populateServiceTypes: "kfontviewpart.desktop" specifies undefined mimetype/servicetype "fonts/package"

And finally:

kbuildsycoca4(47941) KBuildSycoca::save: Saving
kbuildsycoca4(47941) kdemain: Emitting notifyDatabaseChanged ("servicetypes", "xdgdata-mime", "services", "apps")

The latest 9 PBI of kdevelop starts both from the command prompt and menu/desktop shortcut. You will get an error about the git plugin being disabled if git is not installed.
