Juggernaut Error

I am doing one application for that i implement chat thing using
maccman-juggernaut-0.5.9 here when i was run the juggernaut -c
juggernaut.yml i get one error "syntax error, unexpected ':', expecting
keyword_then or ',' or ';' or '\n' (SyntaxError)
        when :broadcast: broadcast_command"
please help me for these.

Is that the complete error message? I would have expected it to tell
you which line of which file caused the error. Copy and paste the
whole command line and error output here.

I am guessing that the error is in juggernaut.yml. Check the syntax
carefully, make sure you have not got any tabs in it (only spaces).
