You probably already had jack coming from Fedora. It is (sort of)
incompatible with the Planet CCRMA jack when it comes to realtime
permissions. 

Look into /etc/security/limits.conf, most probably you will see there is
also a limits.conf.rpmnew. Edit limits.conf to match the rpmnew version,
logout and login again and all should be well.
