First of all, it hasn't been updated since 2003, secondly it wouldn't install for some reason, but thirdly, I don't really mind that it didn't install because, looking back, as part of the installation it was installing Lingua::Stem modules for half of Europe. That's way over the top for what I wanted to do.
1) HTML::Index doesn't attempt to install any modules
2) HTML::Index only requires Lingua::Stem
3) If you're having problem installing HTML::Index, there is very little hope you'll find any solution to your problem.
