rtmpdump on osx ... problem compiling

[bricula]

first of all: hello everybody, I am new to this forum, but I cannot solve the problem by myself...

I have a mac intel 10.5.8 and I need to download a rtmp file from the net. I have already the url (got it from a firefox plugin) but I can't find any software for download it, shareware or freeware...
I tried everything I found on google... flazr, rtmpdump and others that I don't remember (my trash bin has been empty)

Flazr seems to me a little bit too complicated, so I tried this softare here, rtmpdump.
I have installed the xtools from the osx dvd, without problems, I open terminal, "navigate" to the rtmpdump folder and I typed make posix....

make[2]: Nothing to be done for `all'.
gcc -Wall rtmpdump.o librtmp/librtmp.a -o rtmpdump -lssl -lcrypto -lz

error!!!!
same result with rtmpdump 2.1c, 2.2c and 2.2d..... and the readme file sucks, if I can express my opinion...
so... have I missed a fundamental option, that is stated nowhere?

the thing that makes me mad is that I spent only a couple of hours to do so on Win... and there are 2 days that I search a way to do the same thing on the mac. bill vs steve 1-0.. and I am very sorry to say so...
Please do not tell me to download with parallels or with windows, because the mac is my fathers and he's a bit stubbon concerning the use of win on the mac...
any suggestion?
