Flickr Api integration problem

I have gone through the rflickr README, and it says to get the token.
I have struck-up here with getting auth.token.

My script looks:

require ‘flickr’
FLICKR_KEY = ‘f8ecb4b6ef8c94934034e04c79d645db’
FLICKR_SECRET = ‘daa2d9158df1458c’
FLICKR_CACHE = “#{RAILS_ROOT}/config/flickr.cache”

flickr = Flickr.new(FLICKR_CACHE, FLICKR_KEY, FLICKR_SECRET)

unless flickr.auth.token
frob = flickr.auth.getFrob
puts “#{frob}”
link = flickr.auth.login_link
puts
puts link
puts
puts “copy and paste the above url into your browser then hit enter
after viewing the page”
gets
flickr.auth.getToken(frob)
flickr.auth.cache_token
end

My code is breaking …

ERR: Invalid auth token (98)

Any help will be appreciated.
