erro no mon

Boa Noite pessoal

Quando tento levantar o mon da o seguinte erro:

[root@cluster-master cript]# service mon start
Starting System Monitoring daemon (mon): cf error: could not use PAM authentication: Can't locate Authen/PAM.pm in @INC (@INC contains: /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 .) at (eval 4) line 1, <CFG> line 14.
BEGIN failed--compilation aborted at (eval 4) line 1, <CFG> line 14.

[FALHOU]

Alguem pode ajudar ???
