Claudia won't start - complains DBUS is missing

[cleinias]

Launching Claudia from either the Cadence panel or from terminal produces an error message

"DBus is not available, Claudia cannot start without it!"

But DBus is installed, as far as I can tell:

better will be you post the error-outputs from terminal here, like this:

with a fresh build of ladish, claudia works now
