Here's a session with "make sandbox" that shows a version bitmap:

----------------------------------------------------------------------
You are running in a dummy Open vSwitch environment.  You can use
ovs-vsctl, ovs-ofctl, ovs-appctl, and other tools to work with the
dummy switch.  

Log files, pidfiles, and the configuration database are in the
"sandbox" subdirectory.

Exit the shell to kill the running daemons.
