Simply put, you give a page more pagerank by linking to it more frequently. If you organise your internal links into a pyramid structure then you will naturally give category pages more internal pagerank than pages within this categories. E.g.
Home >> Category (each category linked sitewide, links to current subcategories and back to home) >> Subcategory (linked from the current higher category, links to parent category) >> Page (linked from the subcategory, links to parent category).
The picture becomes more complex, because it is external links that provide your site with pagerank to distribute. So, if it's only the homepage that gets links, and you're only links internally are from your hierarchical links, then distribution will be even. but if others pages get their own external links, you won't have even distribution.
The other question is why you would want a totally even distribution? Primarily, the goal is to ensure pages have enough juice to appear for the keywords and phrases you target. Even distribution based on a hierarchy is only a good starting point.
This can be thrown on its head by one simple deep link to one of your content pages. I have seen sites where some internel pages have more pr than the homepage.
