[rudloff@…]

It seems you can't install dbus if you are not root:

Is there any workaround around this ?

[rudloff@…]

Oh, sorry, I didn't see the no_root variant...

[neverpanic (Clemens Lang)]

Can we find out whether the current MacPorts installation is a non-root one and change the default_variants accordingly automatically? That would prevent this from happening to unsuspecting users.
