I've now edited my post with the link recommending the perl downgrade. I originally tried using the default perl, and Logitech Media Server failed. Preferably I'd like to keep two versions of perl installed. The system version would be the current perl available from the repos (5.20.2), and the older version only used by Logitech Media Server. The latter would be installed at /opt as per the -Dprefix flag in ./Configure (and the link recommendations). However, if I can't get this to work, I'll attempt to modify the sole perl install as you suggest. Thanks for the advice.
