Using 20131101 emacs-snapshot,

$ LC_ALL=C emacs-snapshot -Q &

In scratch buffer, type

(setq ispell-program-name "hunspell")
(setq ispell-dictionary nil)

and `eval-region' that region. Then run 'M-$' on a couple of words (file and
dictionary). This will make ispell.el be loaded and ispell process started,
messages buffer shows

Starting new Ispell process [hunspell::default] ...
Checking spelling of FILE...
FILE is correct
Checking spelling of DICTIONARY...
DICTIONARY is correct

Evaluating in the scratch buffer

(message "%s" (assoc nil ispell-hunspell-dictionary-alist))

I get (now default here is en_US)

(nil [[:alpha:]] [^[:alpha:]] ['0-9] t (-d en_US) nil utf-8)

Note that `ispell-hunspell-dictionary-alist' is not bound until ispell.el is
loaded, and that will not happen until you spellcheck for the first time (or
call a command that forces ispell.el load), so the first part of your check
should do nothing until then. If you get some result there please doublecheck
that you are not loading it from a different site.

PS: What is prin1?
