@Bomp right, but I think it should work on Mac OS already. I might try it inside VM, but this is sorta hassle now :) I would be glad if someone try to run it on Mac OS

excellent... and how can I use this downloader?

Check that you have ruby, rubygems and hpricot gem installed, if something is missing install it.

Then

$ git clone git://gist.github.com/882022.git simpled
$ cd simpled
$ ruby simpledesktops_scraper.rb

You propose to setup a whole infrastructure to use just one little downloader :-)

Why, yes I am. Don't like it, don't buy it, it's small utility thing after all, everybody can write their own for theirs infra, amirite?
