I asked the CIDER folks and they said: CIDER relies on autoload for a number of features to reduce startup time. Emacs Live doesn’t seem to support package.el’s approach to autoloading so a bunch of CIDER functionality is not available out of the box.
You can M-x eval-expression (require 'cider-browse-ns) and then the cider-browse-ns command is available… however most of it doesn’t work, no doubt due to other dependencies that aren’t autoloaded.
I opened this issue against Emacs Live with more details:
