Nginx SPDY: Missing NPN Extension in SSL/TLS Handshake ?

Hi guys, I've tried setting up CentOS 6.4, Nginx 1.4.1 with Google SPDY
support and used spdycheck.org to check the site and all SPDY checks pass
except this notice:
Missing NPN Extension in SSL/TLS Handshake
Sorry, but this server is not including an NPN Entension during the SSL/TLS
handshake. The NPN Extension is an additional part of the SSL/TLS
ServerHello message which allows web servers to tell browsers they support
additional protocols, like SPDY. SSL/TLS servers that don't use send the NPN
Extension cannot use SPDY because they have no way to tell the browser to
use SPDY instead of HTTP.
What exactly am I missing from Nginx 1.4.1, openssl 1.0.1e and SPDY setup to
properly satisfy NPN Extension in SSL/TLS handshake ?
Chrome reports SPDY support fine though.
