Can't fine mime.parse

[Haines Brown <haines@HistoricalMaterialism.info>]

I installed emacs-w3m and put these lines into .emacs:

        "~/elisp/w3m/"

        (require 'w3m-load)
        (require 'mime-w3m)

In ~/elisp/w3m there is, i.a., mime-w3m.el. 

However creates an error because w3m is looking for mime-parse.el:

  Debugger entered--Lisp error: (file-error "Cannot open load file" "mime-parse")
  require(mime-parse)
  (progn (require (quote cl)) (require (quote mime-parse)) (require (quote mime)) (require (quote w3m)) (defvar mime-preview-condition) (defvar mime-setup-enable-inline-html) (defvar mime-view-mode-default-map))

  load("~/.emacs")

  call-interactively(execute-extended-command nil nil)

There is available a mime-parse.el, but I had assumed that this was
automatically a part of emacs 23. Should I go ahead and install
mime-parse (along with its dependencies: mime-def, luna and std11)? My
intuition is that this is not necessary just to get emacs to desplay
html files with w3m.
