That is a strange use of the word "yes".  I'd call that "no", unless
you are talking about a CVS tarball instead of the last released one.

The spec file from AUCTeX CVS is not supposed to need tweaking.

Here is the respective package from the CVS spec file:

%package emacs
Summary:        Enhanced TeX modes for GNU Emacs
Group:          %{commongroup}
Requires:       emacs >= 21
Obsoletes:      ge_auc emacs-auctex auctex preview-latex-common 
preview-latex-emacs
Conflicts:      emacspeak < 18
Provides:       auctex

Note that our RPM does _not_ provide preview-latex-common (which LyX
expects) since it does not install preview.sty into the teTeX tree.
For this purpose, there should be a separate, independent package in
the spec file, which isn't the case now.

(info "(auctex) Advice for package providers")

Note that we do not follow our own advice with regard to the
preview-tetex package: it is still missing.  That makes it impossible
to run LyX in parallel with current versions of AUCTeX and teTeX 2.0.
I don't know how many installations of teTeX 2.0 are around, however.

Wrong in the version _I_ was talking about since preview.sty is not
installed into the teTeX tree, so texhash is unnecessary.
