logger_fatal: command not found

I'm having the following problem after running: /bin/sh install.sh

install.sh: line 164: logger_fatal: command not found
install.sh: line 165: logger_fatal: command not found
install.sh: line 166: logger_fatal: command not found
install.sh: line 167: logger_fatal: command not found
install.sh: line 170: logger_fatal: command not found
install.sh: line 173: logger_fatal: command not found
install.sh: line 174: logger_fatal: command not found

Can anyone shed some light on this one? Let me know if you need any other information.

I have the following operating system:
cat /etc/redhat-release
CentOS release 5.3 (Final)
