5.13 not fetching email

[Aaron Larson]

I just upgraded to ubuntu hardy emacs-snapshot 22.3 running gnus 5.13
and when I attempt to read mail, it no longer fetches.  I don't get a
request for the password either.  If I use emacs 22.1.1 with v5.11
everything works just fine.  Here are some excerpts from my .gnus
file:

(setq gnus-select-method 
      `(nnml ,(getenv "MAILHOST")
             (nnmail-spool-file         ,(format "po:%s" my-email-user-name))
             (nnmail-pop-password-required      t)
             (nnml-directory       ,(expand-file-name "Mail" 
gnus-home-directory))
             (nnml-active-file     ,(expand-file-name "Mail/active" 
gnus-home-directory))
             (nnml-newsgroups-file ,(expand-file-name "Mail/newsgroups" 
gnus-home-directory))))

(setq mail-source-primary-source `(pop :server ,(getenv "MAILHOST") :user 
,my-email-user-name))

Has anyone else seen something similar?
