Problem compiling rtmpdump 2.3 on Mac OS X: Undefined symbols: _EVP_sha256

I tried to compile rtmpdump on my OS X 10.5.

When compiling with

make SYS=darwin

I get

Quote:

gcc -o librtmp.0.dylib rtmp.o log.o amf.o hashswf.o parseurl.o -lssl -lcrypto -lz -I/usr/local/include
Undefined symbols:
"_EVP_sha256", referenced from:
_InitRC4Encryption in rtmp.o
_InitRC4Encryption in rtmp.o
_HMACsha256 in rtmp.o
_RTMP_HashSWF in hashswf.o
"_main", referenced from:
start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[1]: *** [librtmp.0.dylib] Error 1
make: *** [librtmp/librtmp.a] Error 2

Then I changed the "SYS=posix" lines in the 2 Makefile-s to read "SYS=darwin" and then it (seemed to) compile using just

make

But when I run rtmpdump I get

Additionally the rtmpsrv crashes with a bus error as soon as it receives traffic:
