bug#2339: 23.0.60; Blinking Cursor Won't Blink (Mac OS X)

I'm unable to get the blinking cursor to work on Emacs 23 (Mac OS
X). Changing various settings makes it blink until you move point, at
which time it no longer blinks.

In GNU Emacs 23.0.60.1 (i386-apple-darwin9.6.0, NS apple-appkit-949.43)
 of 2009-02-03 on skinny.local
Windowing system distributor `Apple', version 10.3.949
configured using `configure  '--prefix=/opt/local' '--with-ns' 'CC=/usr/bin/gcc-4.0' 'CFLAGS=-O2' 'LDFLAGS=-L/opt/local/lib' 'CPPFLAGS=-I/opt/local/include' 'CPP=/usr/bin/cpp-4.0''
