$ grep "use lib" check_*
check_breeze:use lib "nagios" ;
check_disk_smb:use lib "nagios" ;
check_file_age:use lib "nagios";
check_flexlm:use lib "nagios";
check_ifoperstatus:use lib "nagios" ;
check_ifstatus:use lib "nagios" ;
check_ircd:use lib "nagios";
check_mailq:use lib  "nagios";
check_rpc:use lib "nagios";
check_wave:use lib "nagios";

Yep...  How unfortunate that the one I chose to base my plugin on is 
check_file_age, which does not have this.
