I can't figure out if spdy is already packaged with nginx 1.5.1 or I have te recompile it. I installed nginx with the following command passenger-install-nginx-module this installed nginx 1.4.1 without the spdy module compiled into it.
The php-fpm will just work on the nginx installation but passenger and spdy have to be compiled into the binary.
I hope anyone can point me to the right direction about how to compile nginx with both passenger and spdy support.
