I think Julian Tarkh's solution is the easiest. But if you must do it in ruby, you can use 
the Find module.

Paraphrased from the Ruby Cookbook (pg216):

require 'find'
Find.find('./') do |path|
   Find.prune if File.basename(path) == '.svn'
   puts path
end

In irb:

irb(main):001:0> require 'find'
=> true
irb(main):002:0> Find.find('./') do |path|
irb(main):003:1*   Find.prune if File.basename(path) == '.svn'
irb(main):004:1>   puts path
irb(main):005:1> end
./

Without the Find.prune, you'll get everything:

irb(main):001:0> require 'find'
=> true
irb(main):002:0> Find.find('./') do |path|
irb(main):003:1*   puts path
irb(main):004:1> end
