I'm using the documentation that came with the application bundle.  
Anyway I removed the auctex package I installed and added the above  
lines. Emacs chokes on (require 'tex-site). Spotlight fails to find  
tex-site.el anywhere on my system. If aquamacs comes with auctex  
preinstalled, surely it must come with a copy of tex-site.el.

I installed auctex using the installer available from http:// 
yaced.sourceforge.net as suggested by the Aquamacs documentation.  
There is nothing to make, it comes "pre-made". My understanding is  
that the job of the installer is to take care of the usual configure/ 
make process automatically.

This produces the following:

An error has occurred while loading `/Users/cameron/.emacs':

File error: Cannot open load file, tex-site

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

I don't have this directory structure. Spotlight is unable to find  
auctex.el. All this is confirming for me that AucTeX does not come  
pre-installed with Aquamacs and simply needs to be activated.

Of course, I could be wrong :-) Perhaps I deleted something I  
shouldn't have from /Library/Application Support/Emacs. So I  
reinstalled Aquamacs from scratch. None of the above results changed.

Okay time to review. First up I remain unconvinced that auctex/ 
preview-latex comes with aquamacs. Unless these packages are  
installed by the user, aquamacs will use tex-mode. Second, after  
installing auctex using the installer described above, aquamacs will  
then use auctex when visiting a tex file without any further  
customisation required the user AS LONG AS auctex is installed to / 
Library/Application Support/Emacs or (despite what the documentation  
claims) $HOME/Library/Application Support/Emacs. BUT preview-latex  
does not work.

In my reply to Paulo I mentioned that I had got Preview to work when  
I installed to ~/Emacs. In the above tests I removed these from from  
load path. It seems that the above experimentation broke something as  
now I am unable to regain the set up that did work earlier.

Okay. It's not worth this much work! Thanks anyway for your suggestions.
