e-blog does nothing

[ken]

Excited to have a sensible interface to (google's) blogger, I downloaded
and installed e-blog.  Per the README I ran "M-x load-file RETURN
~/emacs.d/e-blog.el RETURN", then "M-X e-blog-new-post RETURN".  Then I
was prompted for username and password.  To this e-blog responded "wrong
type argument: stringp, nil".  Thinking this might be e-blog's way of
saying that I mistyped the password, I tried the username/password
prompts again (i.e., reinvoked "M-X e-blog-new-post RETURN").  After
doing this several times with exactly the same result, I finally got this:

------------------------ begin -----------------
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  call-process("curl" nil "*e-blog*" nil "--stderr" "/dev/null"
"--header" nil "http://www.blogger.com/feeds/default/blogs";)
  (let (feed) (set-buffer e-blog-buffer) (erase-buffer) (message
"Requesting list of blogs...") (call-process "curl" nil e-blog-buffer
nil "--stderr" "/dev/null" "--header" e-blog-auth
e-blog-fetch-bloglist-url) (setq feed (buffer-substring ... ...))
(message "Requesting list of blogs... Done.") feed)
  e-blog-fetch-bloglist()
  (e-blog-parse-xml (e-blog-fetch-bloglist))
  (e-blog-setup-choose-buffer (e-blog-parse-xml (e-blog-fetch-bloglist)))
  e-blog-choose()
  (if (e-blog-check-authinfo) (e-blog-choose))
  e-blog-do-auth()
  (progn (e-blog-do-auth) (e-blog-choose))
  (if e-blog-auth (e-blog-choose) (progn (e-blog-do-auth) (e-blog-choose)))
  e-blog-new-post()
  eval((e-blog-new-post))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp)
  recursive-edit()
-------------- truncated --------------------------

So what's the problem?

Thanks,
