Actually, save your money and drive time to Seattle:

require 'rubygems'
require 'image_science'

in_file = File.expand_path "~/Desktop/logo.gif"
out_file = File.expand_path "~/Desktop/logo-thumb.gif"

ImageScience.with_image in_file do |img|
   img.thumbnail(50) do |thumb|
     thumb.save out_file
   end
end

So, 2 things were wrong, you need to use File.expand_path and you  
need to match the case of the directory names (although OSX is a case  
insensitive file system, this is just a good idea).
