rtmpdump does not require ffmpeg to build.

I don't get it. You can't link ffmpeg successfully, but you have a
binary to show us which reports its version? Then it must have been

You see, I don't understand the problem. Even if you were trying to
compile ffmpeg with librtmp support (the other way around from what
your first sentence says), where do you have that binary from?

Are you sure that did a "make clean" before running ./configure with
new options? This seems like librtmp was found at configure time 8and
possibly compile time), but not at link time. Your installation of
librtmp may be borked, e.g. by two conflicting versions.

A good start would be to show us the full command line and output of
your ./configure call. Then there may be some hints in config.log.
