I have basically the same configuration as yours ---Ubuntu 12.04, Emacs 
23.3 from distro repository, TeXLive 2012 and AUCTeX from CVS.

(The difference is that I also have TeXLive 2009 from Ubuntu 
---Debian--- repository to satisfy dependencies and Emacs 24.1 from 
gnu.org, which I compiled in $HOME/bin. In both Emacs ---23 and 24--- I 
installed AUCTeX.)

Now ---from what I see here

when you installed TeXLive 2012 you asked it to install symlinks in 
/usr/bin, which I don't do and I think is in general not a good 
practice. But anyway, the strange thing is that LaTeX is not found:

[...]

(it is the configuration of preview-latex that checks for LaTeX); and 
even stranger that the command line does indeed find LaTeX:

As I *prepend* TeXLive 2012 to my PATH (I don't use symlinks in 
/usr/bin), the config.log of AUCTeX has, for example,

    > configure:2841: checking for pdftex
    > configure:2859: found /usr/local/texlive/2012/bin/x86_64-linux/pdftex

and the config.log of preview-latex

So, what I think you should do is *prepend* 
/usr/local/texlive/2012/bin/<your-arch>-linux to your $PATH. I do it in 
/etc/environment:

> PATH="/usr/local/texlive/2012/bin/x86_64-linux:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

with the “disadvantage” that I have to `` sudo su '' to use tlmgr to 
update. The other way is to put TL 2012 path in your ~.bashrc, as 
suggested in Jim's link.

You have to log out or restart once you have set TL 2012 path as desired.

The equivs trick is to satisfy dependencies for packages (e.g, Kile) 
installed via apt-get or Synaptic, but it's not needed to install AUCTeX 
from CVS.
