The problem is because my emacs version is still 21.X, need to update with dumpemacs.
bash-3.2$ sudo mv /usr/bin/emacs-i386 /usr/bin/emacs-i386.orig
bash-3.2$ /usr/libexec/dumpemacs -V
22.1
bash-3.2$ sudo /usr/libexec/dumpemacs -d
Checking if emacs is up-to-date
emacs is not up-to-date. Needs dumping
...
bash-3.2$ emacs --version
GNU Emacs 22.1.1
