Centos 6.5 and ECDH ciphers in nginx.org Centos repo

RHEL used 1.0.0 in 6.4, however in 6.5 it was updated to OpenSSL 1.0.1e-fips 11 Feb 2013
See: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.5_Release_Notes/

Like I said, if I compile nginx myself it ECDH works fine. It’s the nginx.org binaries that do not work. So it would appear the nginx.org binaries are statically compiled against the older version, so I guess the question is when will the nginx.org builds be built on 6.5?
