I think this version of bbn that you have lots of errors in it. I too faced a lot and had to correct the code at many places. Try the other latest versions.  You can download them from the CGRAN website. Download douggeiger and the uspr versions. I personally installed the douggeiger version on my computer. I am not sending the link as the cgran's website seems to be down. Google it and you will find it.

Does anyone meet this problem? Thank you very much
