Netgraph and Netflow-v9

It appears that it may be something with my current collector.  While
debugging today, I decided to attempt to run Silk locally on the FreeBSD
netflow box.  

When exporting locally, it is reading the netflow-v9 records.  Yay!

Our collector is an older Linux box with a manually compiled current
version of Silk (not that it should matter which OS is running on the
collector) with the libfixbuf patch installed.  I wonder what is going on
there, alas, that is not your problem :)

Thanks for the help!
