hmm, the 'path' parameter refers to path for control-sflow-to-rrd-handler
rather than the path for sflow-to-rrd-handler.  So you will need to change

program         =>      'sflow-to-rrd-handler',

to:

program         =>
'/usr/local/ixp/tools/runtime/sflow/sflow-to-rrd-handler',

The reason this works on our systems is that sflow-to-rrd-handler is
located in /usr/local/sbin/, which is in the standard daemon $PATH
environment variable.

Can you see if this works?  If it does, I'll open up a github ticket to
make a note to fix this properly.
