[Nagiosplug-help] nagios-plugins 1.4.8 + sudo = can't find utils.pm?

[Ugo Bellavance]

Hi,

     I just upgraded nagios-plugins to 1.4.8 using the rpm package from 
rpmforge: nagios-plugins-1.4.8-1.el4.rf and I have a problem...  Every 
check that is done using sudo (check_mailq and check_clamav) returns:

Can't locate utils.pm in @INC (@INC contains: nagios/plugins

The solution is to add 'export PERL5LIB="/usr/lib/nagios/plugins/";' in 
front of every command definition in nrpe.cfg, but I don't consider it 
as a permanent fix... it was working fine with the previous version of 
nagios-plugins (1.4.5).

Anyone has an idea of what could be wrong?  Please let me know if you 
need any other information.
