Basic CMS for bookmarks (delicious clone)

Question

I am looking for a basic open source CMS to build social bookmarks site like delicious.com. I need just basic functionality:

1. Users should have pages like site.com/username where titles and links for the bookmarked sites will be displayed.
2. Ability to check who else added a specific URL to the bookmarks.
3. Bookmarklet to quickly add a site URL to the bookmarks.
4. RSS for the users bookmarks.

I do not need tags, comments, ratings and other complex functions.

I'm looking for the solution for three days in a row but many projects are closed or are not maintained for a long period of time.

I'm not a programmer but I can tweak PHP code, HTML and CSS. So it will be better if CMS is written in PHP, but other languages and frameworks (like Ruby on Rails or Django) will be fine too if the CMS is simple.

Thanks for the answers!
