Seven steps

This tutorial may be incomplete – I set this up from my system, which already has a lot of libraries and packages installed. The readme recommends glib, gtk, gtksourceview2 and such – YMMV.. This is what -I- had to do.
# eselect ruby set ruby18
# layman -S
# layman -a gnome

(if you are running on amd64)
# echo “dev-libs/libgee ~amd64″ >> /etc/portage/package.keywords/common
# echo “dev-lang/vala ~amd64″ >> /etc/portage/package.keywords/common

# emerge dev-libs/oniguruma dev-libs/libgee ruby-gnome2

AND HERE’S WHERE IT BIT IT. I couldn’t build ruby-gdkpixbuf2 against Ruby19 and I didn’t feel like uninstall Ruby19.

# gem install oniguruma activesupport rspec cucumber hoe open4 zerenity

I guess I’ll have to wait a little longer for this machine. I do have an old laptop running Ubuntu – and redcar gives detailed Ubuntu installation instructions.

As is, this code will create an array of arrays – Directories with the same 6 first characters will be grouped in the same sub-array. I am using this for log directories, name format 20081125 for instance – you can just replace the logic to be whatever you need, of course.

dirs = []
Dir['*'].each do |item|
  if File.directory?(item)
    if dirs.empty?
      dirs << [item]
      next
    end
    inserted = false
    dirs.each_with_index do |list_of_folders, index|
      if list_of_folders[0].to_s[0..5] == item[0..5]
        dirs[index] << item
        inserted = true
      end
    end
    dirs << [item] if !inserted
  end
end
