EIN on Aquamacs 3.0 not working

Question

After starting my iPython Notebook server in Terminal, I try:

M-x ein:notebooklist-open RET

this gives following error:

defvar: Symbol's value as variable is void: c-mode-syntax-table

(source: ein documentation )

I'm at a loss how to debug/fix this.

---

I just got the newly released Aquamacs 3.0, and installed the required packages (websocket, request, auto-complete) before installing the ein package.

Preferences.el include (probably redundant with Aquamacs 3.0):

(require 'cl)
(require 'websocket)
(require 'request)
(require 'ein)

I am on Mavericks, have been using emacs for ~2 yrs.

EDIT

for completeness sake, at request of lunaryorn:

This is a guess, c-mode-syntax-table is defined in cc-mode.el, it seems ein uses this somewhere in its code, can you do M-: (require 'cc-mode) RET and try again.
