The /user/local directory is site-specific and usually locally-installed stuff; software and tools and libraries that have been installed into the Unix environment.  That directory doesn't usually have any OS X files in it, unless somebody copied something there.
In this case, some software expects a DNS update tool to exist in the /usr/local directory, and it's not there or not there anymore, and some other piece(s) are trying to start the operation via launchd, and failing.
The source of the tool looks to be www.dnsupdate.org, though that site is offline right now.
Do you want or need help putting the dnsupdate stuff back, or possibly removing the launchd widget that's trying to activate the (missing) tool?
