I followed Kano's instructions using a newly instantiated CentOS 6.4 server on the Amazon Cloud service.

There is a problem in step 6 where where you copy and rename http://www.openssl.org/source/openssl-1.0.0j.tar.gz

The patches in /rpmbuild/SOURCES are out of sync, because they still correlate to the original source from http://vault.centos.org/6.4/os/Source/SPackages/openssl-1.0.0-27.el6.src.rpm

My journey is documented here http://bitcointalk.org/index.php?topic=239337.msg2568979#msg2568979
