PageRank in 5.0.1 from 5.1.1

[pozycjoner]

Hello,
I have Indexu directory v. 5.0.1 and it hasn't PageRank module. Of course, I can download Indexu 5.1.1 with PageRank, but I want to use version 5.0.1. I copyed googlepr.php and pagerank.class.php from version 5.1.1, but it didn't work. How I can add PR module to 5.0.1 version?

You need to add new table:

CREATE TABLE `idx_pagerank` (
