Well ... this post has me confused on several levels. First ... I think you mean Linux Ubuntu (not Lunix Ubunta). And second, if you're using Ubuntu, why are you using ActiveState Perl? I know that ActiveState Perl is available for Linux but I would recommend using Ubuntu's repository (apt-get/aptitude) for installing perl packages first and then CPAN only if the package is not in Ubuntu's repository. As you can see, using yet another perl package manager just muddies the water.
