dbus 1.6.8_0 activation failure

[michi_ca@…]

Mountain Lion 10.8.2 with lastest XCode. Completely uninstalled macports with these instructions: ​http://guide.macports.org/chunked/installing.macports.uninstalling.html Installed Macports again, then installing wine-devel I get this (tried 3 times, no folder in /opt apart from X11 after uninstall):

Error: org.macports.activate for port dbus returned: Image error: /Library/LaunchAgents/org.freedesktop.dbus-session.plist already exists and does not belong to a registered port.  Unable to activate port dbus. Use 'port -f activate dbus' to force the activation.

I tried also

port -f activate dbus

but to no avail

Unfortunately some ports, in this case dbus, install files with unusual names in unusual places which our manual uninstall instructions do not cover, in this case /Library/LaunchAgents/org.freedesktop.dbus-session.plist. You can either manually delete that file, or use force the activation (sudo port -f activate dbus) to have MacPorts move the file(s) with conflicting name(s) out of the way for you. Can you elaborate on how sudo port -f activate dbus did not work? It should have. If not, run it with the debug flag (sudo port -df activate dbus) and see if there are any errors.
