I recommend you install tmail library(gem install tmail)
If you installed tmail, you can try this:

require 'net/pop'
require 'tmail'

Net::POP3.enable_ssl(OpenSSL::SSL::VERIFY_NONE)
Net::POP3.start('pop.gmail.com', 995, username, password) do |pop|
  if pop.mails.empty?
    puts 'No mail.'
  else
    pop.each_mail do |message|
      string = message.pop
      mail = TMail::Mail.parse( string )
      if mail.multipart? then
         mail.parts.each do |m|
           if m.disposition
             filename = m.disposition_param('filename')
             if filename[0,2]=='=?'
               filename.gsub!(/=\?[^\?]+\?(.)\?([^\?]+)\?=$/){$1=='B' ?
$2.unpack('m*') : $2.unpack('M*')}
             end
             puts filename
             File.open(filename,'wb') {|f|f.write(m.body)}
           end
         end
      end

    end
  end
end
