I downloaded the following:

http://emacsformacosx.com/emacs-builds/Emacs-pretest-24.3.92-universal.dmg

Simply mount the disk image (by double-clicking on it) and open the file "
Emacs.app/Contents/MacOS/Emacs".

Unlike earlier releases, the "Built on" field is marked as "Multi". This
might be something that "emacsforosx.com" has added to the installation,
although I find it unlikely, as they typically provide clean Emacs
installations.
