Installing Perl Based Package

I'm having a heck of a time installing a perl based package (etree-scripts: https://launchpad.net/~ketilwaa/+archive/etree-scripts/+packages). I've made my way through a few problems so far. At first I was getting this:

perl Makefile.PL 
Can't locate ExtUtils/MakeMaker.pm in @INC

Based on some Google'ing I did the following:

wget http://files.directadmin.com/services/9.0/ExtUtils-MakeMaker-6.31.tar.gz
tar xvzf ExtUtils-MakeMaker-6.31.tar.gz
cd ExtUtils-MakeMaker-6.31
perl Makefile.PL

Which then led to this:

Can't locate DirHandle.pm in @INC

I found a discussion here that pointed to the following package, so I did this:

wget http://www.readynas.com/packages/readynas/perl-modules_5.8.8-7.infrant2_all.deb
dpkg-deb -x perl-modules_5.8.8-7.infrant2_all.deb /

Then I could at least run Makefile.PL on ExtUtils, but when I got to the Make step, I get this:

make: *** No rule to make target `/usr/lib/perl/5.8/CORE/config.h', needed by `Makefile'.  Stop.

I get the same message if I try to Make on the etree-scripts package. I Google'd this for awhile and all of the suggestions seemed to be dead ends to me. Any suggestions? I use Linux quite a bit, but when it comes to this type of manipulation, I consider myself a novice. I looked in /usr/lib/perl/5.8/CORE, and there are no contents to that directory.

I found this thread: http://www.readynas.com/forum/viewtopic.php?f=35&t=58321, but when I do CPAN -v, I just get cpan: command not found.

Thanks for any advice!
