Thanks Luis.  The "Error opening capture device" error is gone.
However, when I try to run it as nonroot against scanme.nmap.org port
80, I get this repeatable failure starting on the third probe:

I'm not sure if this is due to trying to bind the same source address
or what.  But it doesn't happen for me with the trunk nping:
