I have installed Nginx in our redhat machine using rpm. Now we want to add nginx-rtmp module, but inorder to add new module as per the document i need to build it by downloading the tar ball. Does it mean that i have to remove the rpm and install it as per the document.

Ref: https://github.com/arut/nginx-rtmp-module/wiki/Getting-started-with-nginx-rtmp

./configure --add-module=/usr/build/nginx-rtmp-module
make
make install
