Anyone has the rtmpsuck worked well on Mac OS X?

[notono]

Is there anyone who succeeds to have rtmpsuck worked on Mac OS X (10.7.3)?

The README instruction in the rtmpdump distribution saids:

> Based on reading the BSD ipfw manpage, this rule ought to work on BSD:
> ipfw add 40 fwd 127.0.0.1,1935 tcp from any to any 1935 not uid proxy

However, the ipfw command in Mac OS X seems not to support `not uid' rule.
How can I write ipfw rules for rtmpsuck, or is there any other idea to have rtmpsuck worked on Mac OS X as a transparent proxy?
