I live by CPAN.pm, it is awesome. I just didn't try

perl -MCPAN -e "install 'PDF'"
[download]

But now that I am looking at the modules they dont look to useful. They seem to be total alpha modules basically for reading pdf files. I dont see yet how to create one from scratch, although Text::PDF claims to be able to. And I dont see any examples yet. I am going to keep hacking.
