rtmpdump (Mac) Need Help with Compiling

[mickymouse]

I have a mac version 10.8.2 mountain lion.
I downloaded the RTMPDump source tarball from http://rtmpdump.mplayerhq.hu/ and got the rtmpdump-2.3

I read the instrucitons on this website http://trick77.com/2010/07/31/captur...dump-mac-os-x/
but I don't understand it since this is my first time using terminal.
What i did so far is cd desktop/ and then cd rtmpdump-2.3
...and i pretty much don't know what to do next since i don't understand.

Can anybody help me with the instruction that is written on that website? http://trick77.com/2010/07/31/captur...dump-mac-os-x/
And What I should write on the terminal?
