devd problem after recent upgrade

[AN]

I just upgraded to svn r263756 and have a major problem, the system has no 
mouse.  When I reboot I see the following message on the console:
devd:devctl sysctl missing from kernel

then

/etc/rc.d failed to start devd, and also I had to run dhclient em0 to get 
the network started.

I have not added to or changed any config files.  Has anyone else seen 
strange behavior like this recently?  Any help would be appreciated.
