rtmpdump should use MacPorts zlib and openssl

[ryandesign@…]

rtmpdump uses Mac OS X openssl and zlib. It should instead use MacPorts openssl and zlib.

$ otool -L /opt/local/bin/rtmpdump
/opt/local/bin/rtmpdump:
	/usr/lib/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0)

This means the port can currently only install on Snow Leopard; see #24562 for what happens on Leopard.
