init failure

[Max <maxim.suraev@xxxxxxxxxxxxxxxxxxx>]

Hi.

Recently my emacs start failing initial loading with following error:

Debugger entered--Lisp error: (file-error "Cannot open load file" "calist")
  require(calist)
  (progn (require (quote cl)) (require (quote calist)) (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))
  eval((progn (require (quote cl)) (require (quote calist)) (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)) nil)

  load-with-code-conversion("/home/x/.emacs.d/init.el" "/home/x/.emacs.d/init.el" t t)
  load("/home/x/.emacs.d/init" t t)

It seems like it's w3m to blame.

Question is - what is "calist" (I don't see it in package list) and which file
exactly is missing all of a sudden?

thanks,
Max.
