Your perl setup is screwed. You should only have one version directory
in @INC. Not all from 5.8.0 till 5.8.5.

It isn't the module that isn't looking, it's perl. You should install
RRDs.pm in one of the directories perl has in @INC.

This one?

That points to a badly installed librrd.so.2. All your problems are due
to a bad installation of RRDtool. We aren't the people who know how to
do that right. And there is probably nobady here who knows CentOS. I
found out from Google that CentOS seems to use RPM packages. Why don't
you try to locate an RRDtool RPM for CentOS and try to use that?

The easiest way is to use ready-made packages.

I would like to advise you that you should use a more common platform.
When you use an exotic one like CentOS, you should be able to help
yourself. If you can't it's probably better to ask people who know the
platform. I've never met anybody who uses CentOS. I could help you with
Debian, Ubuntu, SuSE Linux or Red Hat. Or Solaris and FreeBSD. But then,
you could probably install RRDtool and Munin on all of those without
running a single make command.

Sorry about this.

PS: One last hint. Have you ever tried to answer the question why the
    linker can't find librrd.so.2?
