The Snow Leopard and Lion buildbots were just reinstalled (yesterday?) on new (virtual) hardware. So they probably have no users created by MacPorts ports now and will be getting them recreated as ports are reinstalled.

The dbus port used to use adduser and addgroup in a pre-activate block. In r96635 this was changed to use add_users, but the port's revision was not increased, so the package the buildbot fetched did not contain this, and was still trying to use adduser and addgroup. I would have thought this should still have worked...

...except in the case of the no_root variant. Note how the comment in the pre-configure block says "Value must be set in pre-configure because dbus_user may change in variant." The add_users directive being called from r96635 does not take this variant into consideration. Not relevant in the buildbot's case since the buildbot isn't requesting that variant, but I thought I'd mention it.

I wanted to quickly updated dbus to 1.4.24 to see if the buildbot would build that, but I can't even build it on my system. There's a ticket for updating to 1.6.8 which just needs a better patch attached; hopefully that will work.
