Ummm....  It can't find the file "netbios.rules" or "./netbios.rules".
Put in the full path to the file that you intend to use and that error
should be fixed.

But...  You'll have another error then.  Save yourself the time and simply
configure the snort.conf that comes with Snort.  Simply fill in HOME_NET
with the subnet that you want to watch and set EXTERNAL to !$HOME_NET (not
HOME_NET).  Then for the other plugins, you can configure them, but for
testing, you'd be fine to leave them at your defaults.

Hope that helps!
