I had a similar problem with RHEL. The issue was with the modules. The best outcome is installing from the DVD and letting it install all dependencies along with it. Since our RHEL was a corp load, we were also missing some core modules for the ones needed by eStreamer. It was a painful process, but eventually found everything we needed. It's not an issue with the cert because eStreamer will tell you that.
This (IO::Socket::INET configuration failederror:00000000:lib) is telling me that this module is not loading properly.
Running: netstat -nt and look for port 50655 for an established connection to DC. This will tell you the tunnel is actually up after it makes the initial connection.
Sorry I couldn't pinpoint your problem, but it took me (and Cisco) a while to find all the issues with our installation.
