Ruby Net-SFTP Unresponsive

Question

I'm trying to upload a file to a SFTP site using Net::SFTP.

The problem is the Ruby process never returns. It's frozen, stuck, never-ending... I have to Ctrl-C to make it stop.

I can connect to the ftp server in the command line using sftp.
I've tried this code on Linux (Ubuntu) and Snow Leopard and it does the same thing.
Installed the latest version of Net::SSH and Net::SFTP.
- From gem list net:
  - net-sftp (2.0.5)
  - net-ssh (2.1.4)
Different combinations of hash arguments (see code below)
Tried to call Net::SFTP.start instead of creating a SSH session first.
Server responds with "SFTP protocol version 3" when I login using a command line tool and ask for the version.
I'm running Ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10.7.0]

Debug output from :verbose (last couple of lines):

D, [2011-07-29T17:30:52.693834 #19399] DEBUG -- tcpsocket[80c06478]: sent 52 bytes

Sample code:

require 'rubygems'
require 'net/sftp'

FTP = "someftpsite"
FTP_USER_NAME = "user"
FTP_PASSWORD = "password"
hash = {:password => FTP_PASSWORD, :verbose => :debug, :keys=>[""],:auth_methods => ["password"], :timeout => 5, :port=>22}
begin
    Net::SSH.start(FTP,FTP_USER_NAME, hash) do |test|
    test.sftp.upload!("localfile","remotefile")
end
rescue Exception => err
    puts "error:#{err.inspect}"
end

Edit: 8/22/2011

This seems to be related to the interactiveness of the SFTP server. I solved this by creating a shell script using expect and shelling out from Ruby to run the file. The shell script is created at run time. This seems really hackish, but it's the only way I've been able to make it work using Ruby. If anyone else has a suggestion, I would love to find a better way to do this.
