ERROR: unable to find either group "stapdev" or group "stapusr"

[Dave Nomura]

Are these stapdev and stapusr groups something new or have I stumbled 
into part of stap that requires them? 
I am using a pretty recent SystemTap snapshot.

I don't recall seeing anything about them in the documentation and 
apparently didn't need them when using an older version of SystemTap.
