Net::SNMP Perl module?

Hello,

I am fairly new to Net-Snmp.  I use it on some Solaris servers to give me CPU, Memory, and Disk stats (for MRTG to use).  It also came pre-installed on my RedHat 3 server.  I use that server to run MRTG and BigBrother (network monitoring).

Anyway, one piece of BigBrother is a module that uses Perl to do some SNMP work.  The docs say:

"bb-xsnmp.pl requires the Net::SNMP Perl module include with the NetSNMP package formerly known as UCD-SNMP."

I am running...
snmpd -v

NET-SNMP version:  5.0.9
Web:               http://www.net-snmp.org/
Email:             net-snmp-coders@lists.sourceforge.net

I know that's a slightly old version, but it came with RedHat, and is working so far, so I'd rather not upgrade unless needed.

Anyway when I try to run the perl module...
./bb-xsnmp.pl
Can't locate Net/SNMP.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

at ./bb-xsnmp.pl line 9.
BEGIN failed--compilation aborted at ./bb-xsnmp.pl line 9.

So it looks like it's having some trouble finding the perl SNMP module?  Was my version of Net-SNMP possibly not compiled with that option?  Or is it just something I have to add on?

Thanks,
