Playing around with Mod Cluster and following the documentation at http://docs.jboss.org/mod_cluster/1.3.0/html_single/#Quick_Start_Guide
Following section 2.6 I started my httpd /opt/jboss/httpd/sbin/apachectl start
The httpd was from the FULL Httpd, Mod Cluster, SSL bundle they have up for download.
Got the error: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory.
