What is the 'risky' in Emacs?

Question

I'd like to start Emacs on Mac OS X.

When I run 'emacs' comamnd in terminal, I got the error;

signal(error ("Unknown keyword :risky"))
  error("Unknown keyword %s" :risky)
  custom-handle-keyword(package-load-list :risky t custom-variable)
...
..

What is the 'risky'?

I just install 'Starter Kit'.

How I solve this problem?

===== UPDATE

This error only occure in Built-in Emacs on Mac OSX Terminal.

In GUI Emacs(GNU), It works.

Here is full trace of error.

===== FINALLY

Install emacs 23.2.

Everything works fine.

If this happens before you do anything, launch emacs with the --debug-init option. That should tell you where the error is occuring. — harpo
I had the same problem, installed emacs with homebrew, removed /usr/bin/emacs (which was version 22 anyway). Seemed to fix it. — mrmagooey

Remove the starter kit, start fresh.

As harpo commented, to debug your actual problem, try starting Emacs with --debug-init, which should provide a stack trace showing what line caused the problem.

But really, get rid of the starter kit.

If you want to start using Emacs, check out all the other questions folks have asked about beginning Emacs and try some of the tips for beginners folks have already given. Of particular interest is a question about starting with Ergo Emacs, which is essentially the same thing as starting off with the Starter Kit.

UPDATE

From your stack trace, it looks as though the version of custom that the starter kit expects is newer than the version shipped with the Emacs you're using on the Mac. The risky is a keyword for defcustom, which was added in Emacs 23.1 (see NEWS.23.1). So, either upgrade your Mac's Emacs, download a newer version of custom (may not be possible at this point), or remove the starter kit by commenting out (require 'package) in your .init.el.
