The Bug Genie 3 requires PCRE librairies 8.0 or later. You have
version 7.8 2008-09-05. Update your system to the latest release from
your usual sources.
On my Centos 5.9 I could upgrade pcre from 6.* to 8.* no problem but could not get it "recognised" by PHP or Apache. Problem solved itself by upgrading php53 to php54
