elpaca fails to install ddskk because ccc installed version (0) lower than min required 1.43

[amano-kenji]

Elpaca is not tolerant of version issues.

ddskk comes with ccc. That means ddskk should set ccc's version.

This is my workaround for this issue.

(use-package ccc
  :ensure (:version (lambda (_) "1.43")))
(use-package ddskk
  :config
  (setq skk-keep-record nil))

I just had this same issue with notmuch and ol-notmuch.

I did

  (use-package notmuch
    :ensure (:version (lambda (_) "0.38")))
  (use-package ol-notmuch :ensure t :after notmuch)

But, could somebody explain me what the issue really is? I know notmuch is pulled from git so version is not really 0.38 but still don't understand why ol-notmuchfails while other packages have no problems?
