Both EL-4 and EL-5 zabbix EPEL testing packages have wrong paths to zabbix_server and zabbix_agentd (/usr/bin/..., should be /usr/sbin/...). The Fedora packages don't seem to have this problem. Also, the just built EL-4 package is 1.4.2-2 and EL-5 is 1.4.2-1 which means there's an upgrade path problem - I suggest bumping both to 1.4.2-3 while fixing this.
