Missing lib location for default Nagios path

[CorbMax]

I've got this error when installing this plugin:

(No output on stdout) stderr: Can't locate utils.pm in @INC (@INC contains: /usr/lib64/nagios/plugins /usr/lib64/nagios/libexec /usr/lib/nagios/plugins /usr/lib/nagios/libexec /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/nagios/libexec/check-netapp-ng.pl line 43.

Please add this use lib "/usr/local/nagios/libexec"; to the script to support default Nagios location when installed from source
