--------------------+--------------------------------
 I tried to install the emacs_app variant of auctex with macports 2.2.0 via
 the following command:

 `sudo port install auctex +emacs_app`

 The installation failed:

 {{{
 --->  Computing dependencies for auctex

 Error: Failed to configure auctex, consult

 }}}

 In the log, I see:

 {{{
 :info:configure checking for gs... gs
 :info:configure checking for latex... NONE
 :info:configure configure: error: LaTeX not found, aborting!
 :info:configure You must install LaTeX for preview to work.

 --with-emacs=/Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs
 :info:configure Exit code: 1
 }}}

 My mistake is that I only have the texlive-basic port installed, which
 doesn't provide LaTeX.  But I think the port should check for this case
 and go and install the appropriate port(s) so that LaTeX is present,
 rather than failing.
