I'll be happy to once I get it up-and-running :)

Thanks for clarifying!

How do I explicitly enable libtool 2 when I compile? Here's the
version of that libtool that I have on the system now (and when I
compiled 5.0):

    tom at millhouse:/opt/collectd/sbin$ sudo dpkg -l |grep libtool
    ii  libtool                          2.2.6b-2ubuntu1
                  Generic library support script

I don't see an explicit libtool option for the configure script. Is
there something I'm missing?

Thanks! I set my IncludeDir value to "/opt/collectd/share/perl/5.10.1"
and restarted, so I'm not getting that error any more. Unfortunately,
I'm now getting this error:

I found a few posts that said I should run this before I start collectd:

    export LD_PRELOAD=/usr/lib/libperl.so.5.10.1

However, this didn't seem to help. Am I getting this because of the
missing libtool dependency? Also, why do you suppose it's looking for
a Perl 5.10 plugin if I'm using 5.10.1?

Thanks again for all of your help Sebastian!
