OK.  But if you look at the command that does the byte-compiling in the 
auctex sources, it includes `-l lpath.el'.  The contents of lpath.el are:

;;; This file is only used for installing AUCTeX.
;;; It is not a part of AUCTeX itself.

;; Make sure we get the right files.
(setq load-path (cons "." load-path)
       byte-compile-warnings nil
       TeX-lisp-directory "<none>"
       TeX-auto-global "<none>")

By re-byte-compiling without this, we run the risk of messing something 
up.  So I still think it's wrong to call __prepemacs on this package. 
If you don't like my suggestion of providing src_postinstall, then I 
think there should be a different way for cygport users to have some 
control over the postinstall process.  What about defining variables 
(like PREPEMACS, etc.) that allow the user to turn the __prep* functions 
on or off?

That seems like a good idea.  But what about packages that include 
addHyphen commands?  I'm not sure whether formats have to be rebuilt 
after such packages are installed.  In any case, there's probably 
something that needs to be done for such packages.

I don't think so.  The only non-texlive package in the distro that adds 
anything to /usr/share/texmf is gnuplot, and it only adds a .sty file 
and a .cfg file.
