It all results in the same error.

I get this with screen-256color, but also with xterm-256color and xterm.
Depending on how I logged on.

I still don't understand how I should provide the requested features.
Could you elaborate on that?


I just searched a bit further, it also happens with "emacs -nw
some-file" when there is no .emacs file present, or if it contains only:

    (custom-set-variables)

But if that .emacs contains just one setting like this:

    (custom-set-variables '(auto-insert-mode t))

The problem is gone. Fascinating!

So to summarize:

emacs -nw -Q some-file, shows "Symbol's function definition is void: 
regexp-opt-group", does not load some-file
emacs -nw -Q          , shows "Symbol's function definition is void: 
regexp-opt-group"

In both cases, I can continue working.
