The `return_to` arg should NOT be `signed`, it should be the originating URL where you initially logged in.

Also, I dunno what the assoc_handle is doing spitting out an arg like `{HMAC-SHA1}{49cdce76}{BhuXXw%3D%3D}` it should be processed further. I have the needed perl packages installed (latest for Lenny). Hrm, would endianness matter?
